Banned for No Reason

Over a month ago now I purchased some MUT Points during a break at work. After work in the evening I found myself banned from the Auction House. I appealed this as soon as I could with EA, but am still banned.

I am very confused by this as I don't play online, so don't cheat, and don't buy or sell coins. I literally just play the solo part of the game and then bought the points. Then got the Auction House ban. I got some really good cards from the packs when I opened them, 99s and Ltds worth millions and millions, but could sell them. They are now a fraction of the price, so very disappointed and angry about the whole thing.

Does anyone know how long it will take to have this ban lifted? As I say, it has been over a month now and I've heard nothing! Would I be likely to get any in-game compensation? I have lost out on a huge amount of coins and feel very wronged as I gave EA money and they then, for no reason, took a large and key part of my game away from me.

I am ranting, sorry, I don't want to sound whingey. Probably too late for that.
