Extremely Bad Service

I have been a customer of cell c for the past 14yrs + and I haven't been finding joy with their service, I have 2 cell phone contracts plus 1 Sim card (data) contract with them.. I was due for an upgrade in March 2021, I did the upgrade and up until now in September I haven't received anything, and I when I followed up with them, I found out that I have been billed for whatsapp and for other services which I didn't even agree to! They are deducted all those monies but I don't receive the service for what I'm paying for. They recently sent me a message stating that I must pay R2100+ which I queried and that's when I found out that I was being overcharged and for something which I didn't assign to.. And now that I took reversed my money they decided to suspend my services!! But no one has came back to me to tell me about the reason for all this overcharging and the fact that I haven't received any phones that I upgraded to! Because when I spoke to Nthatisi who is the Agent I asked her to Escalate the matter for me and no correspondence has been done but such a drastic decision has been taken! Helo Peter I really need Cell c to be dealt with ASAP!! Since it's not the first time I wrote a review (complain) about them
