Shocking Service from Marquis Finance

I closed my account with Marquis Finance in April 2025 and they called me on the 24th of February 2026 and said that I did not pay an instalment for a month as they claimed that I received the wrong amount on my settlement letter. I spoke to the consultant to let them know that the settlement letter was correct with the correct that and they said they will take this up with their manager, it’s the 14th of March 2026 sending countless messages to the consultant and info at Marquis and nobody is helping me after sending countless emails even to the complaints email. This is shocking and unacceptable behaviour from a company, I am beyond shocked that this is how you treat a customer who has closed their account and received paid up letters multiple times. I am shocked at the lack of professionalism from Marquis Finance.
