Cash send reversal

Forgot my bank card at home so I decide to do a cash send, I get the C code go to the Atm to retrieve the funds, get error message voucher cannot be redeemed, make 2 attempts and make a call to call centre and the lady I spoke to tells me that they cannot reverse the transaction. What googled the mind is that Capitec is the last of all the banks to have a cash send facility and I am unable to reverse transaction from the same banking app. Ridiculous that I have to wait 30 days, these were the last funds in my account and now stuck unable to get the groceries I was trying. Had the reversal been available, could have gone to get my card and proceed to get my groceries... Guess no supper tonight, thanks a lot , and you call yourselves the best digital bank in the country, probably all the staff was voting. 30 days is not being unique allowing customers the ability to reverse their own transactions provides CX, have been contemplating switching maybe this is the proverbial straw....
