Extremely rude and questionable business practice

Not only had to pay in full for parts ordering, when I noticed the receipt was indicated as sales and delivered, I went back and ask for putting a note in writing to indicate the "Not Delivered" status. The person behind the desk got so mad and agitatedly wrote it down so hard that torn apart the paper. Then after waiting patiently for a month without the parts. I finally had to go back and ask for the refund.
