This is the worst customer service from Cell C in 23 years!

I had to cancel my CellC accounts debit orders due to internal ***** and I have been paying/making payments into the CellC account every month since then. Since then one of my accounts has not received the data for 5 months. I have made inquiries and sent emails with proof of payments and still no response. I have made several calls and the agents cannot help me. I am also receiving debit order invoices after canceling the debit order, and I have communicated this with CellC. When I do call I have to go through a few questions, if answered incorrectly their agents will not help you. This is the worst customer service in 23 years. My bill is paid on date with no service. Do I have to go to a CellC store to get service? Because Cellc owes me now. I really just want to cancel the contracts and never do business with CellC again.
