Unsatisfied customer

My name is Rasheeda Padayachee-Saaiman. On 2023-02-28 cellc debited my account with R1097, R1023 and R428. I phoned them as I was not aware of the R1097 that was suppose to be deducted from my account. On several occasions they would either tell me they can't assist me as their computers are slow and no one can assist me. My one contract are suppose to end April whereby I already gave notice to close this contract. Again the month of May they deducted the same amounts from me when phoning them all they say is my account according to them that was R398 is not R980 can anyone explain how and an account can go up on the second last month of the contract double the amount. If I do reverse my money at my bank this cell c would indicate that I have missed a payment and it would negatively affect my credit score. This is however not the first time I'm have problems with cellc their service are pathetic. I would not in thismlifetime recommend any friends or family members to cellc because what happened to me can happen to them. I never budgeted for this amounts to go off and like last month I will wait a few weeks before they pay the difference into my account. Come hell or high water I will never renew my contracts with them I will definitely go to a other company. I phoned them again on Friday 2023-04-06 and I was again told their system is slow and they would phone me back and up until today no one phone me back that's how poor cellc services are. I can't evens express how i feel because disappointed is not evens a word to describe the way I feel, because if I didn't have enough money in my account then I would have paid bank charger again and this company cellc don't feel a thing when they just go into your account and debit your money and when they must pay it back they take their time. Pathetic.
