Charged for services not rendered and poor support

I been speaking to Afrihost since 15th of February to migrate my line. An agent assured me that everything would be resolved and that I would not go a day without internet. As requested by Afrihost, signed up with SADV account. Then on 4th March I was told that the SADV was not an option and that I need to sign up with Vumatel as SADV falls under them. I was also charged a pro-rata rate for my new account which I was unable to use. I also explained to Afrihost that the OTN box is not the same, and was again assured that I would not go a day without internet. 15th March came and gone SADV had cancelled the previous tenants account. So I called Afrihost and they explained to that the OTN does not support Vumatel and that they would need to apply for a new installation. It's now 1st of April and again I received an SMS welcoming that my account is active and they would happily charge me for a service that I have not received. I called and was told that there is nothing that they can do, but the ONT *should* be compatible. Clear the technicians are clueless and very unhelpful, because everytime I called I received a different story, had to explain myself 5 times and after they assured me that everything would be sorted, I am now without internet for 15+ days only to be told that they might only look at it after the long weekend.
