Battlefield 4 - Banned from Battlelog after G2A Key purchase

Unfortunately, we can't help with account issues like this here. You will need to contact EA about this. Follow the link that shows what you need to include in your email to EA: https://help.ea.com/article/information-about-banned-or-suspended-accounts

Aside from that, there are two things I'd like to add:

1) It often takes around 2 weeks for accountdisputes to reply, so you will need patience.

2) With G2A, just like many other CD key sellers, you can't be certain that the product key is legally obtained or authorized... and that might result in a whole bunch of potential issues, from not being able to play the game at all (as the key might've already been used; also, EA may disable keys if they suspect that they were initially obtained or distributed by unlawful means) to getting banned.

@tubzipro This isn't EA's fault. Don't buy from G2A as they are a known scam. For future reference buy from sites in the following link instead. You also should contact them to get a refund on this illegitimate key they sold you.
