I ordered a part that said it was in stock. They sent me an email stating the part was on back order. I immediately cancelled my order as I needed the part right away. The charged my Credit Card before having the part in stock. I have requested they refund that money. They do not respond to my emails despite several attempts. Very shady company. I now am disputing the charge with my credit card company as they have refused to do the refund. Too much trouble to risk dealing with them
