This is an update to my previous review on 03/23/14......
I sent two letters--one to the store manager and one to corporate office. I was pleased to receive a phone call from corporate office only a week later. The representative told me that they would go ahead and process the refund to my Home Depot card and that it would appear on my statement in "a few days."
Two weeks later, I phoned corporate office to enquire about the credit, which hadn't posted to my credit card yet. I left two voice messages, neither of which were returned. So, I sent two more letters--again, one to the store manager and one to corporate office.
Magically, two days later, I received an emailed receipt showing the credit was processed in the store. The next day the credit appeared on my credit card statement.
In summary, it took the following to get this refund:
3 in-store visits
4 letters
2 unreturned phone calls
Total time from start to finish: about 2.5 months.
