Transaction issue

I have a problem with payment. I had a payment beneficiary to a Capitec bank account and I have paid that person before. On Monday I also paid the person again however I noticed now it changed to Standard bank, the account number and everything is still the same besides the bank. Thus the person has not received the amount till date and keep in mind I paid in the morning and I did not make the change of the bank.

I called Tyme bank and they told me it will bounce back, till date nothing has happened.
