They cant promise to get back your account - some people have in the past had luck company templates. Guess with massive bans they proberly have u 100% and wont give in.
Scam. Don't waste your money paying for the service, especially if the account was caught up in the recent banwave.
Scam. You will probably receive a template message written in fancy English, part of which can be googled to discover it's been used a lot of times before. If a simple google check can find it, I'd imagine that people in customer support who read those messages for a living can easily see it's bullshit. On top of that that if Blizzard has solid proof that you sold gold or botted, those unban attempts are a complete waste of time and money.
Technically it is not scam, but it is not even close to reliable! The most Perma bans for botting are overtuned to 72h suspensions with random letter on appeal. The most 72h suspensions never get lifted The same apply to the new 6 month suspensions! And these sites do just that - throw random appeal letters, and play the roulette, but with your cash There is dozens of appeal letters, accessible public on the internet, so this is peace of cake!
