Investment Account Issues

Good day, I've opened an investment account with African Bank towards the end of Jan 2025. Since that day I have been a regular on the branches with regards to my funds being allocated properly into my account. On the 27th of Feb 2025 I've transferred R500 from my Standard Bank Acc and my friend also transferred R500 from his Capitec account. The problem is that, my R500 is reflecting on the investment Acc and his is not, as he has added an incorrect beneficiary name with the correct Acc number though. We've been requested to send through proof of payments so that they can allocate the money into the correct account, till that that hasn't been done. Nthabiseng (a sweetheart) from the Menlyn branch did assist in logging a complaint as our query stated that it was resolved, yet the money is still not reflecting. E-mails were sent to: ***, however, that did not assist at all, as it seems like the people in there are just enjoying the back and forth thingy between myself and them. Kindly assist please. I have all the proof of payments.
