MOTOR SPORTS WORLD - NEPEAN, ON

I bought a brand bew atv and a month in with putting 250 kms on the atv the battery died while i was out riding. I take it to the dealership and say while its in being fixed i should get a first service done and say oil and fluids and all is good. A week later i get a call saying its ready i think great i will pick it up right away . Then im told there is a bill for $641 for my service and dead battery! Are you kidding me i have owned it for a month and its brand new with 250 kms on it and they are charging me $100 hr labour to do a service which they failed to tell me they were going to take the bike apart and do valves and whatever else and then tell me the battery is going to be $150 as well... Would have been nice to know there was going to be a ridiculous bill like this before they did the work. I have quotes from other yamaha dealerships that are $159 for the first service and also saying as a good business they would help me with the battery issue seeing that its brand new! Im extremely furious with motorsports world and will never do business with them again and i will certainly never recommend this business to anyone. The way they went about doing good service for a new customer was very unprofessional and im very unhappy to be stuck with such a rediculous bill on a brand new product.
