Telkom Promenade poor sales service

Poor service after I took out a adsl line, the first installation took nearly place two months to happen..after this only to find out it was not the correct line that had been installed another two weeks later to install the proper line the contact was supposed to be 605 rand per month.. I was then informed by the supervisor Wasiema that the first line would be cancelled. The first bill came and it was over 800 rand I thought I was maybe initial charges as the bill reflected to me one adsl line. The second month the bill was over 2000 rand and it is two week later, I have eventually to the store after numerous calls to telkom costing me more money as I had been on the phone for more than a half an hour at a time... whilst in store i spoke with Shamiel Harris who said to me I will have to wait 30 days for cancellation and if the bill should go off I do feel that this is very poor service and very poor after sales service from the promenade store.
