Very disappointed

I used to hear people complain about TELKOM. I have had a contract with them for more than 4 years now i have just upgraded in April for another 2 years which will rwhen the first contract came to an end after 2 years i upgraded. This year i am on my third contract with Telkom which will be a full 6 years with Telkom when it comes to an end.

I am currently paying R289.00 for the new contract, the device is a dual phone. I have been paying 419 instead of 289 which when i check my statement Telkom have billed me for calls to my other sim card, how do one call sim 1 on a dual sim? The calls lasted for more than 13 months and were made 17 times.

When i queried this i was told there is nothing that can be done.

I am so disappointed Telkom. I tried to cancel it unfortunately i will be liable to pay R7000 something.
