Terrible Service from MQF

My vehicle finance has been with Marquis Finance, and i have subsequently traded my vehicle in. The dealership settled Marquis Finance on the 29th November and records indicate that i still have an amount outstanding, despite me sending through Proof of payment.

I have sent numerous emails and into MQF, which have gone unanswered, and cannot get a hold of anybody on the phone.

I am disgusted by this service
