Sounds like you did fine BaldEagl, but there are a few things I would have changed. ('Course, I mighta died with no kills, though, hehe).
When approaching higher cons like that, I don't climb, and I don't WEP. I level for speed, maybe even nose down slightly, briefly, to get to top speed. Don't accel so fast that you are above top speed though, or you'll just have wasted a precious bit of E. My goal is to come in with speed, but lower, to look "helpless", all the while holding more E than is apparant (hiding E). My altitude may be 12K, but my speed allows me to bump up higher at will, making my "useful" altitude closer to 14K. Save your WEP, you'll need it at some point.
Next, I approach the cons, but off to the side a bit, maybe 3-4K out. Don't go under them, make them come to you. My goal here is to get them to chase me. I'm fast, so they need to dive a bit to keep up. Ideally, I want a tail chase that will cause them to drop to my level, to where our speeds equalize. If successful, that will have stolen their alt advantage. I can deal with their positional advantage easier than their alt advantage. That tail chase will burn his E advantage.
Normally, this won't work immediately. They will dive to catch you, and will be faster, so will catch you. When I see them about 2k back, gaining, I turn to the side (usually right). I want them approaching me perpendicularly, or nearly so, so that they are closing fast. Make your turn fairly gentle, but tightening a bit as you go through it. He's faster, so will need to pull harder to stay with you, burning his E. As you finish your 90-100 degree right turn, roll level, and watch him out the side. When he hits D600, pause for a split second, then pull up slightly and roll left.(Barrel roll defense). If he doesn't go for the shot, but instead yo-yo's up, you need to go straight instead (no barrel roll) He'll go up, and then turn to dive back onto your six again. Repeat this a few times and he will be nearly CO-E. Keep your moves gentle, but don't get hit. I'm not trying for shots during my barrel rolls yet, just looking to dodge their shots and save my E. Later, that may change. Get too aggressive too soon, and I usually die.
If I can turn it Co-E, my next move is often to drop a bit (1000 ft) to get speed, and try to get them to attack downward, while I dodge upward on a more or less nose-nose merge. If they fall for it, I will now be above them

If one of them falls for it, but not the other, I devote my effort to the top guy, and often the lower one is out of the fight.
I don't get ultra aggressive against two higher cons. I avoid slowing down, and avoid Rolling Scissors, etc. Try to make your moves smooth, and subtle, saving E. Try to make them chase you, but try to make them turn a bit more than you. If they yo-yo up and left, you go right, etc. Try to keep the altitude you do have, and keep your speed.
If they fly tight together (like wingmen), I treat them like one enemy- but like a longer/wider enemy than normal. If one stays high, I try to take the fight away from him. Make him work to stay above you (he'll have to dive a bit to keep fast enough to maintain his position). If one stays high, I will play the game as described, but will watch for a weakness in the lower con that will allow me to get ultra-aggressive with him, and hopefully kill him very fast, before his buddy can dive in to save him. Normally this is through a few subtle dodges, followed by an aggressive reversal.
Even though this burns your E, The "savior" will generally be streaking in with so much speed that he is easy to dodge. And if you don't kill the first guy, he often pulls so hard to dodge your un-expected reversal that he will be lower than you anyway.
The trick (for me at least), is to stay fast, and to stay as high as I can throughout the fight. I avoid the deck, because once you're there you're out of options. If anything I will try to gain or maintain my height whenever possible.
Keep your speed, make them burn their E by making them go too fast and chase you. Try to equalize the E-states, and seperate the wingmen. If you can sucker them into giving up their E, you just need to sucker them into giving up their angles too. Don't get to aggressive, or fixated on one plane for your shots, but take your shots when you can, and don't miss.
I do die alot this way though, hehe.
