Shocking customer care service

Shocking customer service. When I try and call Marquis finance back it just gets cut off. Nompumelelo sent me an email on the 12 April to advise about my account, which I then rep**** but had no response back, the following week 18th April 2025, I get the same email from another employee Thandi at Marquis stating exactly the same as what Nompumelelo has sent. How does one even resolve an issue like this if you can’t even get the communication system right. The customer service is shocking here. They’ve done a change over with systems however I seem to think this was a take over with the actual bank and debit orders were not taken off by Marquis on the agreed date, now they want to accuse the client of being in arrears when I’ve been trying to contact them back. This is extremely frustrating, this isn’t a bank I would’ve chosen
