Ordered and paid for several items online. Went to the local Advance Auto Parts store that was on my order within 1 week to pick up the items. They handed me the items and receipt. The last item on the list was a lawnmower air filter. I did not order that item and have no lawn mower. So I asked to return it. | The store associate tried to return it, but their system had no record of the purchase. He said that online and the store are two separate companies and I would have to call online customer service. | I was on hold for 20 minutes, then tried to leave my number and a message for a callback, but their msg mailbox was full. | The online site states that returns are allowed at the pick-up store within 45 days. How can I do that? Beware! I cannot be the only one with this problem.
