Cell C ***** service

Hi. I have been a Cell C customer since 2016. I have had numerous contracts with them and have always been a loyal customer. but since last year, I have been experiencing various issues with their service, especially when it concerns payments being made. It's a common occurrence for my services to be disconnected, even though payments are always made on time. I have often had to produce proof of payment to ensure my services have been re-instated. But this too takes a while. Right now, my service has been disconnected for the last 3 days, even after proof of payment has been given. As a pensioner, who also runs an NPO, its imperative that i don't lose internet service. I'm still awaiting feedback from them. this issue was to be sorted out within 24hrs, its now more than 3 days. I would really appreciate if Cell C could please contact me so this issue can be resolved.
