Has anyone had to return new tires?

Good day. I ordered some new tires from Atvtirescanada a couple of weeks ago and had them installed today. They are so out of round, I’m hopping all over the place. I can’t go over 30 mph without jumping out of my seat. Just wondering if anyone had to return tires they ordered online? If so, was it a hastle? I’m trying to find out what to expect when I call them tomorrow. I found their return policy that says as long as the tires are not used, they can be returned. However, I had no intention of returning them until I went for a ride. I see this company is a vender/sponser here. I will post back tomorrow and let you know how good their customer service is.
