Like saying feel blessed you have cancer of the testicles instead of cancer of the brain. Unless you're running at CJ or somewhere, or unless you do zero volume whatsoever and are a major slacker, any AM who doesn't even communicate to you the reason for chargebacks and relevant information like that is not even worth 5 seconds thinking about a future with.
To elaborate on my previous post, I believe OP is at fault here and has only somewhat of a basis to complain (if I were in his shoes, I would be pissed, but I wouldn't be in his shoes because I wouldn't promote Smartdate mentioning Be2 in the ad). Take the loss and obviously don't make ad copy mistakes like this in the future. Not a big deal, it's 1.3k. Yes, 1.3k is relevant even to people who make 50k a month. No, OP is not being fucked over unjustly, IMO. It sucks, but it's a part of the game, and being charged back even 1/3rd of the leads is better than hits many people have taken for making ad copy mistakes.
In OP's defense, however, it's murky territory if the terms and conditions didn't explicitly say no competitor mention in the ads. It should go without saying you shouldn't do something like this, and network terms do state in them it's up to their discretion to determine things like this, so it's really up to you and Azoogle if you want an ongoing relationship now.
I will say that if you were caught promoting Smartdate by telling users it was Be2 and an advertiser charged you back for it, I think a lot of networks, not just Azoogle, would not compensate you for the leads, even networks that historically "pay when the advertiser doesn't pay".
