Poor service

Account is on MR JD Venter's name, but mr Venter's daughter, Mrs CC van der Walt is using it and paying the account. Initially it was a top up account, when she did an upgrade, it was suddenly changed to a charged contract. We have been trying now for the last six months to change it back to top up - no luck. Payment was always done from her account, this month they deduct from Mr Venter's account. When we inquire, they told us we are lying and it is not possible. I had to send the bank statement twice, still they don't believe us, and when you speak to an agent, they are very quick to tell you not to raise your voice, you are not allowed to get angry about Altech Autopage personnel not doing their job, and then the agent just drop the phone in your ear. Altech Autopage service is really going down the drain.
