Appalling Service from Vodacom

I had put in a request to cancel a contract that was expired in January 2022. The notice was served for the month of February 2022 but I was still given an account for March 2022 and was debited for same on the 15th March 2022. After posting the complaint on Hello Peter I finally received confirmation that the contract was terminated as of 31st March 2022. I asked for a reifund for March 2022 and was informed via email that it takes 5-7 working days for the money to be credited. This was on the 17th of March 2022. To date I have not been reunded. I find the customer service from vodacom to be very noncommittal when one is in the process of canceling a contract yet when they sign you up they are so helpful.
