ACCOUNT IN ARREARS | NOT

I am a very patient person but this is the 2nd/3rd time I receive a sms stating that my account is in arrears - and it is not as I make a monthly payment of more than my installment. I am really getting fed up with this incompetency. And then the call center phones and ask what happened, why didn't you pay - I DID!!! I even went so far as to send a payment confirmation last month and still I am getting this sms's. I have sent emails and haven't received any reply or what so ever. This is unacceptable - I will never buy something from Russells or any other store related to Russells ever, and I will make sure to tell everyone I know also not to make use of them EVER!!
