Worst Service from Rain

I asked Rain to cancell the 2 sim cards in December 2022. Rain promised to cancell the 19th hour sim card on 31 December 2022. Rain did not say anything about the 24th hour sim card. What Rain can do best is to go to my bank account on the 1st of every month without attendibg to my requests. I had an internet problem from the 12th of September 2022 until I decided to go to Vodacom in November 2022. I phoned Rain from the 12th if September 2022, promises were made but they were fulfilled. I am still requesting Rain to cancell the 2 sim cards because Rain failed to render the service to me but continue to deduct money from my bank account.Rain should give me the total that I was owing less the payments that I made and give me the correct amount that I am still owing.
