Worst service ever!!!!!!!!!

On the 08 November I bought a car financed by Marquis Finance. On the 08 January I returned the car cause it had lots of technical issues. Been in communication with marquis finance and they advised me to send an email to their complaints department on 21 January 2025, till now no communication from them. They have been deducting end of January and end of February. I'm paying for a car I'm no longer in position of. I can't get afford to get another car cause of these deduction. I was speaking to a guy who I signed the paperwork with. He promised to help me since beginning of January till today. Now his ignoring my calls. When I call the callcenter they are always going to escalate the matter. No one giving me feedback.
