Worst customer service I’ve ever received from any business/company/institution

Tymebank lacks the necessary skills needed to resolve customer complaints. The only thing that their representatives can do when you call is escalate your matter to the relevant department. That so callled relevant department then fails to honour their promises in solving you promise within the given timeframe. I called on the 11th if January 2024 to ask about a transaction (deposit) that was supposed to be credited to my account but never reflected. I was told I would have feedback before or on the 16th of January but on the said date all I received was an SMS saying that my query is still pending. No timeline was given and when I called I got their famous response of “we will escalate the matter to the relevant department”. They also promised to call me back with feedback before the end of their business hours (8PM) but they never called back. I have lost all faith in this bank and seems like my money will be lost for good. I have sent an email with the proof of payment but I fear that even if they resolve the matter I might be asked to wait again before receiving the money.
