Cell C treating me like a ******** 274

Wow Wow Wow.. And again Cell C decided that I am in arrears by R127. 03.. Apparently my contract that I have with them was increased from R599 to R725 end of July 2020... It is strange that I didn't received any correspondence from them regarding the increased amount. My Fibre was cut last night, I even received a email after calling them to find out what the problem was.. The email states that they will charge me for reconnection fees, I will be blacklisted and they will stake any steps possible to recover the outstanding amount of R127.. I thought that I was a respected client of them having 2 other contracts with them as well.. By the way they are paid fully.. So I can for heavens sake not figure out why they would treat a client the way they do..
