Very bad after sale service!

When I purchased my vehicle from webuycars the license had already expired. I was told not to worry about it as it would be settled by them and any fines i get for failure to display before they sort it will be on their account. So lo and behold I got a fine. And now it has been more than 2 months as still I am regularly emailing them to find out if the fine has been settled but the matter just gets kicked around by their staff.
