Cannot get a Refund-***

We cannot get a refund for our money. We transferred my Moms landline 011 475 045 into our name- Raymond Swanepoel in Aug 2015, Acc ***, however they only transferred half the line into our name and we had to pay 2 separate accounts. Old account ***(stayed in my mom's name KA Whitcomb) & new account ***. we also moved house in Oct 2014 and the number changed to ***. We have a credit of R912.09 in the old account (***) & Telkom refuses to move the credit to our new account . My mom lives in the UK so in Aug 2015 she came to SA & we went to the Clearwater branch on 22nd of Aug-we spoke to a lady called Lebo to supply a letter from my Mom saying she authorised the credit to be refunded to us. I have a reference number ***1. we were promised that it would take no more than 2 weeks to refunded however we are now waiting almost 7 weeks, I have tried calling he clearwater Mall branch Tel ***, left numerous messages but no one calls back.<br> Today we went into the Clearwater Mall branch and we are told the request for a credit refund was declined, she cannot help us. We must call the 10210 callcentre. I am extremely frustruatrated & angry
