I been a customer of this company for some time now. I actually open another account with them.
But I am very disappointed the way they charged my account for renting a power generator, they charged my account$1000 for 3 weeks, I could have bought the same unit for $1500 new.
I have over $10,000 dollars an orders, and I have already purchased over $7000 in supplies.
I am going to cancel all my orders, I'm also going to return everything I purchase, that we didn't use. If I need to pay a restocking fee, I really don't care. But this company Home Depot will never make another dollar on me. Whatever I owe ill be paying in full, than close this account.
FYI No help from customer service or management !!
Greed is a sickness .
