Disgusting service!

I called MFC Friday, 13 October 2023, to find out how I could change my debit order date as I've changed jobs and my pay date has changed. The consultant informed me that I need to send an email to ***, and that I need to include my ID number and contact details as well as a copy of my new contract as proof of my new pay date. I did all of this on Monday, 16 October 2023, I included my ID number, a copy of my new contract with it clearly stating that my pay date is now the 2nd last day of each month.

I have been emailing with MFC back and forth since then, them asking me for my ID number and a letter that states my date has changed. This is absolutely and completely unprofessional as I've supp**** my details to them not once but twice. Something needs to be done about this horrible service!!!!! Until now my issue has request has not been resolved!
