Non-existent customer service

I received a call on 23 December to inform me that my account was in arrears. Not due to any fault of my own, but due to Cell C being unable to process debit orders if bank details have changed! The consultant then gave me details of of what amount was outstanding and the ref number to use on payment. I made payment on 23 December and I was assured that the system issues would be resolved. So now I have a message that my service has been disconnected! And to make matters even worse dialing 084135 is just a waste of time. I’ve tried 3 times today only to get cut off after holding for an eternity. Good grief! What kind of business are you running? Absolutely disgusting customer service on top of not providing a service that I have paid for!
