No areas of contact!!!

Hi. My account was suspended by MTN although payment had been made to settle the account. I tried co call MTN directly to query why my account was suspended. However both the call centre and self help services have been shut down. Thus I am unable to get in touch with anyone to sort out my issue. This is unacceptable for a service provider to not provide any means of contact for its customers to contact it. My account is still suspended and I am unable to make use of my cellphone despite the fact that my account has been settled. Please can this be resolved ASAP.
