Customer diservice

I've been waiting for feedback from Marquis Finance collections department for almost a week, I sent an email but no confirmation for receipt. Customer service call centre has been rather poor as well, they are terrible with proving customer feedback and troubleshooting. Just yesterday I had to be on hold for 24 minutes only to talk to customer service agent for 1 minute where they said they'd log my complaint instead of providing feedback during the call, no email correspondence.
