Worst service EVER!!!!!!!!!

I got the Explora on the R749 Price Lock deal (Black Friday offer). Since installation I have had endless problems with my account and call after call after call after call they ensure me that my query has been resolved, but nothing is further from the truth. They cannot seem to tell me what is due on my account (which is in fact, between us on a zero balance) ... hilarious. They keep disconnecting my services and then reconnecting after I contact them, while apologizing profusely. They constantly guarantee me that the matter has been escalated and I would receive a phone call within 24 hours. It has now been 13 days, and guess what... I haven't received a single call back. not even after speaking to several supervisors, did I get any response. I have had tremendous cell phone call expenses, having to contact them daily, sometimes even up to 3 times a day. To top it all, my debit order details was not even loaded (they do not even have my banking details on the system, after confirming that they received my debit order request form) and I had to pay via EFT. I do not believe that they are capable of dealing with the matter and I have absolutely no faith in their commitment to service delivery. Worst service ever!!!!
