Bad dishonest service 🤦🏽♀️

MTN Ceres Branch,Had a sim only deal with them and it’s my first contract with them I was behind and went to pay my account up to date and reactivated my sim and they sold me a new SIM card and told me the sim will work after an hour or so.

I paid my account in full on the 21 July 2022 and went back the following week on the 29 July 2022 I needed them to assist me to change the password. Only to find out that my contract needed to be upgraded or cancelled before the 26 July 2022 and now because I didn’t do that now I’m liable for an amount of R1146.00, because I’m now being charged out of contract what what he said he did try to explain.Now I’m asking them why they never told me this the day I came to update my account. He rep**** by saying he does not know but what he can he see is that whether I cancel I’m still liable or whether I upgrade I’m still liable for that amount. Okay, I get that I didn’t know that my contact needed an upgrade but I when I went there and paid all the outstanding balance worth R1814.00 and I bought a new SIM card and they failed to tell me that my contract needed an upgrade that day I was there before the 26 July 2022? Here I am trying to fix my account and they do me like this
