Suspension of services

Every month my 4 voice lines as well as my 4 data lines are suspended without any reason. I have to call them and ask them to please reconnect all my contracts!,i have emailed them regarding this unprofessional service but have not been successful to determine the problem or to have it fixed. When I call in, i am asked an unreasonable amount of questions in order to be assisted.When I get irritated with the consultant, who has not given me any information that he will need to ask me 10 security questions!! Nor are they apoligising for the error and inconvenience caused.<br> <br> I expect MTN to be more professional with me as a loyal and longstanding customer.
