Telkom refuses to give me what i agreed with them

In February of last year I went to the rosebank mall branch to order a new line, I did this on the weekender package and supp**** all necessary bank details.<br> <br> 3 months later I realised Telkom had charged me interest on an overdue account and were threatening to cut my line. It was thus that I realised that not only was my banking details captured incorrectly but they had also signed me up for the wrong package leading me to pay an approximate R300 more every month.<br> <br> I then went in and had them sort it out, the package and bank details. Telkom sorted out the bank details but didn't sort out the package, I tried further with them but made no progress.<br> <br> In January of the current year I again tried to resolve the issue and was met with rude consultants that knew nothing and people on twitter that promised me feedback and calls from consultants which to date I have not received.<br> <br> I urge Telkom to rectify this matter and reverse out all extra charges made to me over the past year, I also urge them to refer to my initial form which I had signed. I am losing a lot of money and a lot of patience, please can you help me once and for all<br>
