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.
Great customer service
Anthony was very professional and on top of what needed to be done to get my order verified and moving forward.
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!!!
