Pro Bike + Run

I was sold three items that the salesman said would fit my bike. Two of the three would not fit.
The lights were installed by myself, the bell Handel bars and storage pack for under the seat will not fit my bike, the sales person said they would. I went to the store for refund - exchange and was told they would not do it. I also bought a two bikes one 1600.00 the other 1000.00 so I am a good customer .
