call centre agents not clued up

at the end of July I made 2 payment towards my account (2 x R200). Then at the beginning of August I received a sms informing me that my account is in arrears. I then phoned the call center and was informed that i was R45 in arrears and that needs to be paid to bring my account up to date. I also explained to the consultant that i have made 2 payments, of which one will be for august. She then reassured me that this would be fine.<br> So, last week when i went to game to make my payment for the month of September I was informed that my payment due was now R450 instead of the R210. Then during the weekend I got an sms informing me that my account is in arrears. So, as far as i am concerned, I am up to date on my account. So, when i spoke to somebody in the collections dept and told them that, and that i will only pay the next installment beginning of October, i was informed that i have to make 3 (THREE) payment!!! How the hell does this work?? This is not nuclear science!!! So, because i paid \extra"3 days too early it is considered non payment for the following month????? I am highly ****ed off right now"
