Bad Service

I took out a contract with Telkom which stipulated unlimited calling to Telkom mobile numbers for a year. So this was up last year August, which was fine because I received an sms stating I could purchase VAS for R49 a month if I dialed *123# & followed the instructions which I did. This R49 comes off my account on the 1st every month which I get a notification on my phone for, as well as another sms stating that I have unlimited Telkom mobile to Telkom mobile minutes for that month. So you can see my annoyance at the fact that I see this charge for unlimited Telkom mobile calling on my monthly statement as well.... Coz it seems that I am paying R100 for this as compared to the normal R50... so I called the call center which took quiet some days for someone to answer my call in the first place. and then someone who does not even understand what I am trying to say answers & said that Telkom will get back to me with regards to this, its been a month and no one has called... this is quiet sad as seeing I'm up for an upgrade in the next 2 - 3 months & this is the service I have received.... Real disappointed
