Cell C support staff and finance dept are USELESS

Cell C has been the worst fibre provider to deal with...Ive never experienced a company that is this unprofessional. Everything from their support staff, to their internal processes, lack of communication and pure disregard for a customer is unacceptable for a brand that's supposed to be as established as they are.

My issue started with Cell C charging me for a 25mb fibre line at a higher rate. I should have been receiving 50mb service. This started back in 2017. I then picked this error up and questioned why I have been getting charged for a package that I'm not receiving and whether they will be refunding me the overcharging all these years. They responded with a "Congratulations, you've been upgraded" communication, and never responded regarding my refund.

Then on December 30th I received a bill saying I owed 3 months worth of payments for my fibre. I explained to the that payments have been made, and sent the proof of these payments on two separate occasions and was told with 48 hours the payments would be credited to my account I would receive a new invoice with the correct amount, being one months worth of payments. Its January 19th and this still hasn't happened...One of the consultants actually said "it was festive, people are on leave in finance, there's nothing I can do, maybe when they get back they can help you" They've cut my internet and I have sat for nearly 6 hours worth of phone calls and spoken to every consultant and supervisor in the call centre, explaining my issue over and over again with no solutions from anyone. One of the managers on Duty, Jabulani, ignored my requests for a call back to handle the matter, I was told "He knows he needs to call you and he will, he's in a meeting" apparently for 6 hours. When I called later in the afternoon I was told he's gone home.

1) Im owed money for being overcharged for YEARS. 2) The error of their own finance department not assigning the monthly payments in question is not my fault or problem, but they cut my internet despite knowing all these facts which are all documented on email and on their system and on all of the daily recorded phone calls I've had to make. I've contacted Metrofibre who provides the line for the fibre service and they tried everything they can to get hold of someone at Cell C finance to correct the issue, but to no avail. The tickets raised via email regarding my query keep giving the same 48 hour response and then the ticket gets closed without the error being resolved.

How useless can a company be in a simple request which concerns their own error?? Cell C is the worst service provider. Get your story together!!
