Money still taken with incorrect cvv

I attempted to order food on 7 Aug 2020 from Mr delivery. I entered the cvv number incorrectly at payment stage. FNB sent me a sms stating that the cvv was wrong and order cancelled. The order automatically cancelled on Mr delivery as well but fnb still allowed my money to be taken even with the incorrect cvv. Not one consultant has been able to give me a proper answer just being sent around and now you want to cancel my card. For a bank you SUCK I WANT MY MONEY REVERSED!!!!!!!!!!!!!!
