Not Sorry for the inconvenience

I had to cancel my contract ending with Mtn because they continue to bill you if you don't. Ever since I cancelled my contact my line has not been working. I have sent countless emails and messages on their Facebook helpline and absolutely no one has assisted me since Monday 21 September. The only response I keep getting from different agents is Good day Sir/Madam, Thank you for emailing Customer Care. Apologies for the delayed response and for any inconvenience caused. Please advise if you still experiencing this voice issue? I am expecting important calls, no one can reach me and Mtn just does not care and they are not sorry for the inconvenience because it's not their inconvenience. Have they even checked if my number is still on Rica. How does no one at Mtn know what the problem is or how to fix it. After 15 years with Mtn this is the most pathetic service. Now they tell me to wait another 7days for a response. What kind of service is that?
