Telkom is ****ming innocent ppl

Hey I have opened a Month to month contact by telkom this year 2023 and I received it the 31 of August 2023 the Sim I used just for one month but now I'm getting billed double I have been paying but every month I keep getting statements to pay more and I haven't been using it since last month it was blocked the sim I went yesterday to the Telekom store in south gate to find out what's really going on and I want it canceled, I feel like I have been ****med to pay for something I never use since last month and I must just pay for a sim I'm not using please I don't know what else to do I'm not working and it's unfair towards me when I took the contract out I was told I'm gonna gonna pay r60 every month but not it's r280 and going up the consultant who helped me when told me about me paying more each month. I was told it's only r60 but now it's keep on going up. Yesterday I was told at south gate I'm gonna still be billed for December how can that be when I'm not using the data and that the so was block for a month or 2 now, telkom is ****ming people to pay for something they not using and I did pay everything up yesterday and I was still told I'm gonna be billed for December for a sim that is blocked and data I never used?
