Lawn Mower Parts - Belt cover, Stock #: 203052967

Tried installing on my 170cc and its the wrong part. Can I return and you can send me the right part? Support has been horrendous for this lawn mower. Repair parts are wrong or out of stock and the manual is hard to read. I also need a replacement cover for the air filter and I need to know what kind of filter it takes. I can't find that anywhere in the manual. Ill never buy PowerSmart again.

The ordering process was fine. I just received the wrong belt cover. How can I return it for the correct cover?
Thank you.

Wrong part for my 170CC self-propelled lawn mower.

This is the second time the website has told me the wrong parts for my machine. Why is it so difficult to find the correct part to fix a $400 lawnmower that broke on the very first use?

There are two belt covers shown for my lawn mower model, B8621S, but neither one fits.
