AutoZone Auto Parts

Ordered a part on Sat. Was told it would be in Tues. Tuesday came and no call. I went in and they looked around telling me it's not in yet. Meanwhile I see boxes all over. Several on the counter. One specifically stands out.
Next day, also, no call, so I call them and they say that the part is in. I go in to find that it was the box that I saw the day before and the received date on the receipt on the box was for Tuesday, the day they said it wasn't in.
All the front end manager can say is, "He checked in the order yesterday" as he pointed to the next register which had nobody working at it at the time.
No ownership of the mistake, just finger pointing. Not even an apology.......
From now on, I'm either going to the dealer or to Pep Boys or NAPA!!!!
