Bad service

I am not happy with Celc getmore service. My membership was cancelled in November the 4th 2020. We then reactivated the account, and they will start to debit on the 1st of December, which it happened so.....i went to a restaurant and wanted to claim for a crave form to get a discount of up to R120 for the meal I ordered, which was in March. I was told that my membership was cancelled and they showed me the November date, but I was getting debited but I can't claim for my benefits...they debited again on the 1st of April. I did a follow up and was told that it was cancelled... I then asked then to refund my money from the 1st of December 2020 until April..... I was given a reference number but nothing or any response happened. I kept enquiring and was told the accounts department will contact me till today nothing. So I'm asking if I could get help with Celc refunding me back my money
