MTN suspending my account and unable to explain the suspension for more than a week now

Good day Hello peter i have a problem with my home wifi from MTN ,it has been working fine since i bought it last year April ,i have now relocated to the new province and when i got to the new province i called MTN to say i have changed Adresses in which i did not have a problem with coverage until last week friday my wifi suddenly stopped working .i have been calling MTN ever since last week friday and iam not getting any help . MTN customer service said there was no problem on their side and sent me to another department that deals with coverage i was told there is a suspension on my account and asked Why they told me they will put me back to customer service who needs to check if there are no outstanding payments ,customer service confirmed my account is up to date but said they will log a call for me someone was apparently going to call me , i waited from sartuday no one called i then went into an MTN store there also they were not helpful i was told there is a suspension on my account i need to phone network coverage ,i did and network coverage told me the suspension is not for network i must call customer service again , and when i phone customer service today i was told their systems are down so they cant help me . so now iam tired i just want cancellation
