RCS / Game

These people are so bad they were harassing me of payment even though a payment has been made and now I paid them off and requested them to close the account and requested a paid up letter, I have been calling them for 2 weeks and all they are doing is requesting my information which I have sent to them 2 weeks ago and every time I call them they tell me that the paid up letter was requested and I should have received it in the last 24 hours. That is their song for the past 2 weeks, I do not know what else must I do to get the paid up for my game account.
