pathetic customer service from telkom7861

Telkom is the worst service provider when it comes to system updates and customer service. I had recently upgraded my contract and requested a split billing on the account as two contracts are on one name, and I was asked to send in a letter stating this which I had done before I could even take the upgrade. As usual i have been debited the wrong amount the first month, and then i queried this whereas I was promised that it would be resolved, but this continued for the 2nd and 3rd month. I had made numerous calls to telkom with no luck, as well as visited their store in PMB tons of times . I am so frustrated because now i get messsgaes threatening to hand me over , yet they cannot do their job by simply adding information onto their system. This is not the first time I had experienced service like this from telkom and was hesitant initially to take this upgrade with them out of fear that this may happen again. I am seriously appauled at their service, and it is such a huge inconvenience!
