Very unhappy.Cell C customer of 19 years

I have been a very loyal customer of cell c since their inception into SA since 2001. So over this lockdown period I was unable to pay my account and sent all the necessary documentation through to cell c for a relief package. A gentleman called me and said because I am a loyal customer I qualify to only pay for the usage of my cell phone account during the lockdown period as I was not earning a cent. So I only have to pay for the minutes that I use and not my full account. Which I was very grateful for. Then I get my statement a few weeks ago and they have charged me for 2 months full contracts. I have phoned the call center 5 times, nobody has been able to help me with this matter. When I ask for a manager they say they are all busy and will get a manager to phone me back. I am still waiting. It doesn't end there... I got another statement yesterday stating that I am in arrears by a month on my fiber line. And if I dont pay it by the end of this month my fiber line will be suspended.So I called an agent at the call center for the 6th time to work out terms of payment. We came to a conclusion that I will pay what I owe cell c over 4 months. I get home tonight from work and my fiber line has been suspended. I thought I worked out terms and if I didn't pay it would only be suspended at the end of June. So once again I called the help desk and they escalated the problem to a supervisor who sent it through to the billing department. The consultant said my line should be reinstated by 18.30 tonight the 18/06/2020. I am still waiting. I have been with cell c for 19 years and they treat me like I am not even a customer of theirs. I am highly disgusted with them and I would like a response from top management please. It just seems like nobody knows what is going on and they send you from pillar to post with no joy at all. 19 years of loyal support should count for something!!!!! Stick to your word Cell C.... I am not happy at all with your service...
