Terrible service

I use to be an afrihost mobile data client via my mtn contract sim. The service mostly excellent and when my contract ended I decided to go with afrihost mobile month to month. That also went fine. I then needed a new cell and decided to take another mtn contract and wanted to sign up with the mobile data once again. I received an error and decided to use there live chat and a consultant assisted and told me that i must try again after 2 hours. I decided to give it a day just incase. When I tried it failed again with the same error. I then sent an email which was not even rep**** to at all. I then decided to submit a ticket and one of the consultants rep**** and said they will flush my number out of the system and I should try again in 24 hours. When trying again it still had the same issue. Long story short, I have since been going back and forth too many times to even mention. Still no joy. I asked to speak to a manager of some sort, but still no one has tried contacting me. For some reason I got billed as well. Sent an email to the accounts department, but just as the support, they have not even bothered to reply. This was a very small amount, which I pay additional bank charges for. Once again, unacceptable. This has been a month now. Since afrihost was bought out by mtn, the service really went down the drain. Or perhaps I am too small a fish for them to really put in effort. I really think the staff is *********** and not helpful at all. Awaiting your urgent reply
