Telkom Email suspension Query not resolved #***

Telkom suspended our all our business emails without notification. We have called them for the past 4 days but we are getting nowhere. We were given a reference number yet according to them that reference number does not exist. All the hours on the phone with them have brought is nowhere. They cannot even tell us why they suspended the emails because our line is still working. When you call you are asked call another department and when you call the department they say you must call they say you must call another department. And so we go on and on. Today the response was "we have escalated your request. It will take 7 days". We cant complain out the service because there's none!
