It was an accident

During a session of PL, I accidently, in a sleepy stupor muted one of my friends, and now I cant contact the thier profile and they have been removed from my friends list, I tried to re-request them as a friend and I wasn't able to, it was a complete accident, and I would like to get,back in contact with this player, how can I go about fixing this? Or who do I contact to have this fixed?

Log in> go to friends list> top right tab says "ignore" click it> find there name> remove.

Done ;)

Yo, your the best bro, I spent money on silver to see if I could invite them that way and it didnt work, now I'm out of some money when I could have waited for an answer lol

Lol...fail...I've counted 4 fails today on forums xD
