No After Sales Service

Purchased a new vehicle a month ago, paid for smash and grab. I noticed a mark on the passengers side window and informed Terrence the next day. He promised to get the supplier who did the job to sort it out. After numerous reminders to Terrence I received a call from the supplier who suggested that I remove the marks with nail polish. I informed them that I expect them to rectify the matter seeing that I paid for the job to be done correctly. They took the address of where the car would be during the day and said they would send someone, this was last week. I emailed Terrence last week Friday to once again inform him that the mark remains and that I would like the matter resolved the same day. The email was ignored. I certainly wont deal with a dealership that fobs you off once they have concluded a deal.
