CMH placed Dealership sticker on my car

When my vehicle was returned after a service, I noticed that the dealer had stuck a CMH sticker onto my canopy. If I wanted stickers on my car I would add them myself. <br> <br> I pay CMH Datcentre to keep my car running but they don't pay me to advertise for them. The sticker comes off and this is the endor*****t for the dealership. <br>
