Telkomobile customer support pathetic

Since my account was opened in Dec 2014 the promised 10mb/s 3g signal we were promised has never been more than 400kb/s,we are still waiting for the Telkom technician to call us back after more than a month to discuss what could be done after he tested the signal and confirmed it was non-existent. So since we opened the account we've never been able to use this service.telkom has still not bothered getting back to us after numerous letters and cancellation letters have been sent.Pathetic 3rd world service at it's best!!!My debit order is cancelled and you lot wont get another cent from me.
