Telkom no service

Hi <br> <br> I have a 4 meg Adsl with Telkom and I was at least getting 3.6 megs which I was happy with...my exchange has been upgraded on the 19/11 in parklands tableview and ever since I can't even get 100k. Spoke to 9 consultants just adding notes for the tech guy but nothing is done...some one came out and marked the issue as resolved but still the same. A tech guy by the name of Cecil also said it was resolved today and got a small and to my suprise got home tested the line and I only get 30k speed....even went on Twitter and said it would be resolved. I have no service what so ever. Telkom is so quick to take my money but can't even assist.my father Gordon Africa has given 35 years to Telkom and this is not the type of service he would provide. So disappointing
