Garden Center at The Home Depot

It has all the usual items in this big box chain. I prefer their Behr paint brand over some others (so does Consumers Report). They have a garden center.

We purchased our Christmas tree at this location. The employees were pleasant, cheerful and helpful. The tree was in good shape and decently priced. Hard to ask for more than that. :)

This afternoon we tried to return a clearly defective string trimmer to this store (it was melting the $100 batteries and nearly caused a fire). The woman at the return desk was very nice but the manager of the garden center and the store manager were both incredibly rude, accused us of "overusing" the product and ended up telling us to go back to the manufacturer for assistance.
Honestly I don't care how much you use a product it shouldn't melt the battery and catch it on fire!!! The managers were both over the top nasty and rude and made us feel like we had done something wrong or were trying to pull something over on them even though we had absolute evidence of a seriously defective product. The manager even tried to justify his behavior by saying he had the same product without a problem.....yeah? So that proves there's something wrong with this one!
Will not return to this store again. Whatever happened to "the customer is always right"?
At the very least, be freaking NICE and not a total jerk.
