Account up to date -still no service 3 weeks later

Having returned home after a business trip, I have updated my account 3 weeks and 3 weeks before the amount due date. I noticed my service failed to be reinstated, so visited MTN Rosebank twice, whose service has been outstanding but they have been severely let down by their legal department. I then started corresponding with the Legal department directly on the store's advice. I use the term corresponding out of politeness because <br> I have had one email detailing the incorrect information, so I forwarded my account statement. This was two weeks ago. I am still waiting ...... <br> After numerous emails requesting an update, and a resolution to this matter, I am still waiting. <br> This kind of service is unacceptable. Furthermore, considering a written email was submitted, expecting an accurate response within 10 working days is not asking too much. I think a 'legal' department would be aware of this?
