I did a quick search for HomeSense stores. HomeSense operates 68 stores in Canada. You did not say where you live, but their web site (homesense.ca) has a store locator that seems pretty easy to use.

In the United States, the same parent company operates a chain called HomeGoods. Their site (homegoods.com) also has a locator where you type in your zip code and it will show locations within 100 miles.

If you can find a store close to you, that will probably be the easiest way to get a refund or adjustment. If all of those stores are too far, I would try to deal with the on-line customer service for that chain.

Even though another store might sell the same brand of sheets, the original "selling dealer" should take care of the problem. They got your money to begin with, so they should do the work to satisfy you.

It sounds like you have a legitimate beef!

Good luck.
