HomeWifi off for 5 days with no explanation

A month ago I took a month on month Home WiFi with MTN and it was the worst decision. First when i took the contract i was told by the sales agent that the debit order date can only be on the 4th 7th or 15th on a month on month contract I chose the 4th but the debit order didn't go through on the 4th i had to go to the store to pay cash, when I asked the consultant why the debit order didn't go through she said it normally happens on the first month but the following month it will go through., and i was not happy with that hence i authorized a debit order and did a debicheck to make sure i never have to go instore to pay . Now I have been struggling with connection , I haven't had connection since the 12th of May till today. I have been calling 135 every day and even went to the Westgate shop and still haven't received any assistance. Every time you call you get a different explanations and get promised that it will be sorted soon . I am considering canceling this contract I am actually glad that I took month on month because wow MTN is the worst when it comes to service delivery. I have sent an email to customer service and the complaints department and still haven't received any feedback
