Capitec

I am a client of capitec for years now. On the 15 of March 2023 I made a mistake on a account to pay a company the account was 1 digit of the account number. The money was removed from the account so I did not think anything of it untill the company called to say they never got the payment and from the 23 I could only get to the bank and find out what can be done to get the money back and until today the 4 of April I have NO proper answer as what they doing about it. The Company is calling with and treating me.

I don't know what or whom to ask for help.
