Terrible service from Axxess

I've had a MTN simcard in my iPad for more than a year now with data from Axxess. All of a sudden 2 weeks ago it said no service. After numerous emails to Axxess and visiting MTN, MTN discovered that Axxess apparently transferred my simcard to the CEO of Afrihost, John Austin Williams. Axxess have now suspended my SIM card and it is impossible to communicate with them to get this fixed. The give me the runaround on every email that I send the. Every time it's something different. One reason they stated was that I have a wrong SIM card. Every time I explain to them that what they are pretending is wrong isn't, they come up with another reason. Axxess is absolutely the worst company! In the mean time, I have no access to all my data that is on my account and they just keep on billing me. Horrible experience with Axxess!
