I bought a microwave last year. Maybe within the one-year warranty period?
So I go to look for the the receipt. Guess what?
They self destruct over time.
Yes, after a short period of time the thermal print fades until the receipt looks blank.
And...
They know about it. I called the local store and got the run around.
I questioned the manager and he said he was aware of the 'problem'.
I asked him if the customer is expected to make copies of their own receipts, 'just in case'? He didn't like that.
Then I asked if the customer is supposed to be penalized for the inability of the Home Depot to provide reliable sales receipts. "I'm sorry", he says. "There's nothing I can do".
And... Their in-store customer service is awful.
I've had employees tell me that the item I want is not sold in their store.
I find it and show it to them.
This one time

I call ahead for a pallet of material.
When I get there. No pallet?!?
I find somebody to get it down for me and bring it up front.
They finally get it and bring it up while I finish getting stuff.
When I get to the check-out, IT'S GONE!!!
Where is it?!? I ask them.. "We didn't think you still wanted it"
NEVER. EVER! Get in line unless you are sure EVERY SINGLE item has a bar code on it. It's faster to leave your place in line, find another item and return to line than let their employee help you.
Oh, there's more... ( that belongs in PARF, though )
