On March 24, 2015, the engine was overheating so we stopped at the TH Lube on Sahara & Jones. The problem was either the radiator hose or the radiator cap. The mechanic ordered a new radiator hose from the AutoZone on Charleston & Jones. When the AutoZone employee arrived with the part, I asked about the return policy, "Can the item be returned at ANY AutoZone location?" She answered "Yes" so I purchased the new radiator hose and paid $50 in cash. Later, it turned out the problem was fixed by replacing the radiator cap so there was no need for the hose. On our way home, we stopped at a nearby AutoZone to return the hose but the AutoZone employee turned us away and said "We don't do commercial". As a customer it was irritating and I thought it was a poor customer service. However, I asked him, "which location will accept the return?" He answered, "Russell and Fort Apache" so that is where I went next. But when I got there, AutoZone refused to accept the return and said it could only be returned at the location where it was purchased. At this point I was very angry about receiving such poor customer service. I explained how AutoZone had already told me it could be returned at ANY location. He still refused to help me so I called the AutoZone on Charleston & Jones from where it was purchased. The manager was unhelpful and said it could only be returned at the original location. So I ended up driving 20 miles out of my way which took more than one hour during rush hour traffic just to return a radiator hose that I was told in the beginning could be returned at ANY AutoZone. Very poor customer service all around. I will strongly recommend against doing business with AutoZone in the future.
