Home Depot review: concrete mix - commercial grade - orange bag

I am a retired journeyman mason and purchased many bags of commercial grade concrete mix and the last visit to purchase the concrete one of the bags was hard and unusable. I had returned to purchase more concrete mix and requested to talk to the service manager for that department and explained what I had purchased and that one bag was unusable. This gentleman assumed I was asking for a refund and asked if I had brought the bag back - first of all I slit it to use prior to knowing it was not usable and it weighs 66 lbs. and would be all over the floor and we have a brand new truck. He stated anyone could say what I said and had it around for years. (cost approximately $10-$11) and I have purchased approximately 22 bags already. He wanted me to load it onto the truck, bring it in and the receipt. I explained that this would leave mortar dust all over my new truck, which would harder in the rain and also would leave a trail all the way into the store as it had been slit open to use. I will not return to the store without having some type of apology and the manager suggested it was our choice to use a competitor of your store. I purchase a tremendous amount of supplies from your store.

Sincerely,
Les Ross
