BAD SERVICE in finance department.

I paid my account through EFT payment to TFG end Dec and Jan.<br> On the 17th January I received a call stating that my account is in arrears. <br> I the emailed customer service that I have paid and provided proof of payment. <br> On the 19th a lady phoned and asked about payment again. Nothing was done with regards to the mail I sent on the 17th January 2015. <br> The lady then sent me a mail stating that my proof of payment was received. I paid an amount on 30/01/2015 and the payment is not reflecting. I email the proof of payment to the same lady on the 30/01/2015. I am now paying for sms sent, phone call fee and col.letter???? How must I pay for these admin fees, if I am not even behind on my account?? I refuse to pay any admin fees as my proof of payment was received and acknowledge by your staff.<br> This is unacceptable!!<br> On payment is reflecting and the other one not??<br> <br> Very disappointed customer<br>
