Bad customer service experience

I logged an atm dispute on 7th September 2021. I drew money from an Absa ATM never received the money and received a slip to indicate that the money would be reversed. Called ABSA the next day and they advised that I speak to my bank (African Bank) and lodge a dispute with them.

It is a month later and after numerous call to African bank, I have not received my money and not even a response from the bank to let me know how far they are with my query.

Every time I call, all I'm constantly told is that the query is pending investigation.
