BAD SERVICE! WHY DOESNT ANYONE HELP ME!!!!!

Less than a month ago my contract was passed over to my mom's name, since my father passed away. I got a call that the request was completed and that the contract was now on my mom's name. About 2 weeks ago I received an SMS saying that my account is in arrears. on the 11th November I made a payment at the Nedbank branch like they informed me. I sent the proof of payment to the given address. I also got a call later that day. They said that they received my payment and it has been loaded to my account. Today (20/11/2015) I got a call from CellC. They wanted to speak to my dad and said that my account is still in arrears.<br> I am sick and tired of this bad service. Every call I receive from CellC is a different story. Nothing adds up.<br> Someone needs to give attention to this case. IMMEDIATELY!! <br>
