DirectAxis / MBD disgusting service

Wow what absoutely disgusting service from Direct Axis - I posted previously about my account being paid up in January 2022 and Direct Axis taking a debit order on 12 March 2022. Then I get a call from MBD collections yesterday and today telling me I must pay R3000 even though according to DirectAxis customer service I owe nothing on the account - trying to explain anything to them is like talking to muppets. I am STILL waiting for a refund of the debit order taken on 12th March - I received an email from Saarah Africa in the complaints department (after my post on here), I sent her the required documents and have heard nothing since, even after sending numerous follow up emails. It seems that the only way to get a resolution to this matter is to take it to the Ombudsman and lay a charge of ***** against them.
