Shocking service from Afrihost

I am extremely frustrated with Afrihost. With my recent move to JHB, the Rain sim card in my area was causing major internet connection problems during the day. I asked for a different option and was told Telkom would be better. As migration to Telkom wasn't an option on the website, a consultant agreed to do a migration for me on the system. I asked if I would be charged for the data for the new sim card for the rest of the month in addition to having paid for the full month for the Rain sim card and he assured me I wouldn't. The next thing, I get an invoice and a deduction from my bank account. The accounts guy Sipho is insisting it must be deducted but I can't understand this as I am no longer using the Rain sim card which I paid for and don't believe I should be paying twice this month when I have not made use of the sim card that doesn't give me decent connection. I try ask for a manager and get no response. It's impossible to escalate a customer complaint to any senior. A consultant called Sihle that I just spoke was talking at me and not listening to what I was saying and then mysteriously, the phone went dead after I had waited 15 minutes for someone to answer. This is shocking service and unfortunately, Afrihost will lose a client because they can't sort out a simple problem.
