Scammer. Took money and never sent the part

I've been scammed by this company. The owner GUSTAV KNIEP 0769919706 is a con. I was invoiced for a motorcycle part on the 14/12/2021 and have not received the part. I was promised a refund and has still not been done. He comes up with all kinds of excuses. The courier was at fault. Then he was on leave. then he was off sick. Or he needs to go to the office to check the transfer that has apparently been done. He is a con!!
