Pathetic service from telkom

Dearest Telkom.....I'm fed up with trying to be civil with you guys......and since well your wall is not accessible im gonna tag you on this post....Nobody in your stores is able to help me and they've been logging cases for me for the longest time......in Jan the 5th I went to telkom Festival mall to get my banking details changed so you guys could get your money.....spoke to a lady by the name Pearl and she said she had updated my details but you would only be able to take the money on the 15th feb. ....meanwhile I was in desperate need of a tablet,app**** for a contract with you guys which was approved(after your employee in Telkom southgate advised me to go pay r600 cash at pick n pay for jan since you weren't able to but I decided it wasn't worth it,got a cheaper tablet at a cash price and requested for the contract to be terminated....my statement for jan shows I owe R1200, went to Telkom Mall of africa to get clarity,they called head office and apparently the contract was not cancelled.....they again logged a case and I was told I wasn't supposed to pay at pick n pay for the contract but absa......3 weeks later nobody has called to try and help me.....yesterday I once again went to Telkom southgate to understand why I wasn't called yet and when is all of this going to be fixed,they said the billing department has to be the one calling me ... was told it takes about 72 hrs for them to call me,it's been more than 72000 hours I'm sure since the cases were logged...
