CELL C Still disappoint after years of over billing

I wrote a review last month after struggling with Cell C about my Fibre account I have with them.. I then got a email from Cell C Fibre support that they are sorry about the inconvenience but they don't have any contracts available on their system regarding my inquiry. I also got a reply from someone on my Hellopeter review promising that someone would call me within 24 hours.. It never happend, in fact I received a email promising that I will be billed less agter Cell C have decided to put me on a cheaper more recent priced for the product I receive from them.. So to my amazement I received another R999 account from them end of Feb 2020.. So going on 2 years no answer and no action from them.. And I am a client with 3 contacts at Cell C.. ..
