auto parts warehouse smells like a cont, Internet

I called to cancel an order 5 minutes after placing it over the computer.  I was transferred to customer service and put on hold for over 10 minutes.  When I got them I was told that too much time had passed and that my payment had been accepted.  It was 9 minutes from the placing of my order. 

I was told that it was against company policy to cancel after payment had been received.  Come on now, 9 minutes!!!!! I will have to pay for the part, pay a 20% restocking fee and pay to mail it back.  What a scam.

Stay clear of the company.  I only wish I had read their reports BEFORE placing my order.
