Cell C accounts department a mess!!!!!!!!!!!!!!!!!!!!

Good day. On 01 April I contacted Cell C as my payment was returned - I had been affected by the COVID-19 . I requested that the bill for 01 April PLEASE be split over 3 months, which I would pay together with my next 3 bills. I received no feedback so called Customer Care who said that they would make sure that this is sorted and that the Accounts department get back tome. I never heard anything again and then at the end of April my bank account was credited with the WHOLE amount for April & May!!! I had the April sent back, sent ANOTHER mail and called AGAIN to be told that this would be sorted out - there was not even a note of any request on the system!!!!!!!!! My reference numbers for calls: *** / ***. I have emails sent since 01 April which will be available if necessary. I can not believe that Cell C has not come back to me in over 2 months?????????? This is not the first time I have had problems with this company, I have been a loyal customer since your inception!!!!!!!!!!!!! AND NOW I SEE THAT YOU HAVE LISTED ME ON THE CREDIT BUREAU???!!!!!!!!!!! All 4 of my contracts come to an end soon, I will definitely be moving to another provider. This is absolutely disgusting service!!
