Bought a Tractor, 3 point Quick Hitch, and a Bison...

Bought a Tractor, 3 point Quick Hitch, and a Bison Backblade. The Backblade's position holes were wearing after plowing some snow. About 3 snow falls. I called as soon as I noticed. I sent pictures. They said that they would look into it. I had to call them back 3 weeks later account no call back. 3 days went then I received a call saying the factory was sending a replacement part in the next stock shipment and I would be getting a call soon. Well, that's 2 1/2 months ago. I'm somewhat bothered on customer service after the sale. Good until they got their money...
