Bad customer service

So annoyed by FNB and their pathetic services... Money was paid into my account through the Geo payments i received an in contact and email notification that the money is in my Cheque account and literally 5 minutes later i received another notifications through the same channels that the money was reversed i called the bank they couldn’t tell me what happened nor trace the transaction as in just happened then was transferred to digital banking where i spoke to their agent by the name of Alka and she also can’t seem to see what could have happened she promised that her team leader would be calling me within 20 minutes and two hours later still no call or an email to acknowledge the issue. Every time i call back to find out about the progress of this issue i get a new agent that i have to keep on explaining the issue and mind you i asked for reference number so it will make it easier to trace and give the next agent an idea what was discussed and what is the problem and how far are they with this matter but it looks like the reference number has no importance. So ****ed off with FNB and their worst customer service.
