Failure to protect my money.

So I sent money to the wrong cellphone number which I realised about a minute later, called the call center and was told they cant reverse a Send-imali, and all we can do is HOPE that the money is not withdrawn in the next 7 days. Its sad that I would witness people with other banks being able to save their monies through the help of their banks when they have made the same error. And the bank I chose (Nedbank) tells me to hope and wait to see if the recipient withdraws the money, which means if they did withdraw it I have lost my money. Such inconvenience from such a big institution is just plain ridiculous, how many people in the entire universe make mistakes daily?? When thy adopted the cardless transaction service how did they not also adopt the ways in which other banks use to protect their client's monies??? M done with this **** bank. Secondly I have tried to reverse a debit order 30 days ago via thee Money app and guess what it was not actioned wht is the point of giving me an option that does not serve its purpose?? Someone at Nedbank is in a wrong position to sign off such stupidity that is of no help to their clients. I would not recommend it to anyone ever, I will not be with the bank that leaves no room to make mistakes as mistakes are part of everyone's life.
