Incompetent and Very unprofessional. Took 2 weeks of nagging them to ship the order. I had to pay twice because May cancelled my order without permission. After about 8 phone calls and several disagreements I received the wrong part. Instead of admitting they made a mistake, they LIED and said there is a new version of the part available. This is not true! I sent pics of the Go Kart, a parts diagram, and a picture of the part! I tried to make it foolproof but unsurprisingly they messed up again! They refuse to give me a refund until they receive the part back and inspect it! Keep in mind the part was not only incorrect, but it was used/damaged/dry rotted! I called them out on this, sent pictures and they still don’t believe me! This has been the worst retail experience I’ve ever dealt with! Lies! Excuses! Incompetence! I cannot emphasize enough to find ANY OPTION BESIDES BDX!
