NOT A SINGLE PERSON CAN RESOLVE MY PROBLEM

I received a message from Telkom in November to say I can go upgrade 17 Dec, this was awesome timing as my phone has been giving problems, after standing in queues for hours at 3 different stores, no one could help me and told me to phone the head office (the fact that no one was willing to help me and expected me to phone around is already ridiculous) After phoning in I was told the message was sent in error and I will not be upgraded until January, there was no solution to this simply sorry for the inconvenience. This mistake was not made by me, it was made by Telkom, and yet they were unwilling to fix their own mistake. After speaking to supervisors (all of which were so incredibly rude) I decided to wait till January, today I phoned 4 different stores multiple times to get the information before I drive all the way there, NOT A SINGLE STORE ANSWERED THEIR PHONES. <br> <br> I then went onto online chat to receive assistance and their I was told yet again to phone another department who will also simply tell me to visit the store. How is it possible for a company to have not ONE person capable of decent customer service when I am paying for this service??
