You had something for sale, which was not for sale.
I am neutral on feedback. I wanted to buy some throttle bodies. I saw them on your website. When I tried to purchase, I got a confirmation. Then a few days later after I asked when they would be delivered, I got another email that the order was cancelled. A follow up message about a mistake that this was a mistake and you did not have them to sell.
Still, you did communicate well, so if I see something bi want from you in future, I have no problems dealing with you again.
The fact you ask for feedback, is good. As this shows your customer service is working. My only disappointment is I have to continue my search.
Thanks
