Licensing Fees (bad service)

Recently acquired a vehicle from Affordable Cars and got charged for Licensing & registration and the vehicle was registered but not licensed and further asked to go do licensing on my side as they are a different province.

I then sent an agent to go licensing due to being hectic and now its become a huge back and forth emails and calls with Affordable Cars not will to reimburse the licensing fees, whereby I have been charged for it on their invoice.

Their assistant business manager (Jackie) keeps saying sorry I will check or sorry I don't understand.

This is bad customer service when they already have received their full payment.
