Paid accounts charged \collection fees\""

On 29.03.2016 I paid my RCS Game account via EFT. A few days later I got an SMS saying I was in arrears. I called the call centre and advised a payment was made. They told me to email the proof of payment to an inbox. Great, done, problem solved, right? Nope. Come month end I get my statement reflecting my account is in arrears with no payment reflected AND I have been charged collection fees. After an 18 min call to them, at my expense, an unwilling agent just says I need to forward a pop. Which was already done. she tells me the email and info I sent was insufficient. I asked to be put through to the supervisor and was put on hold for a long time so I hung up. Nobody ever calls me back, but funny enough I then get an email from the pop inbox telling me to send another pop... So, you had my info for over 15 days, knew it was insufficient and you don't call me to verify or anything, you just charge me more collections fees. Now you have compromised my credit report because of your lazy and *********** employees! I want my collections fees removed, account closed and credit recorded cleared! ****ed off!
