I put 2 of the same orders in due to a web page error and shortly after I was contacted by Deb from customer service asking if I meant to place both orders. She was very helpful, the email was very well written and it genuinely made me feel better about the whole experience. She resolved the issue quickly and with there not being much of customer service these days I was very happy so see that is not the case everywhere!!!

Customer Service.
I recently had to cancel an order with Propel Parts, and I was thoroughly impressed by the prompt and efficient service I received. Steven handled my request with professionalism and speed, ensuring a hassle-free process. I've purchased parts from Propel Parts before and have never been disappointed. Their consistent reliability and excellent customer service keep me coming back.

Everything fine, thank you. The only thing with which I had a problem in your Software, is that when I have more than 10 different items on the list, I can't scroll to the first ones. But besides that, I am very happy in going on with buying your parts.

Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!

Online order. I had a good experience this morning I placed an online order and everything went smoothly. The staff at propel parts has always been helpful in the past when I have been looking for harder to find parts or something that wasn’t listed online.

I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it… This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order. I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
