100% excelente
rapid response!
Excellent and prompt response.
Propel parts team helped me greatly regarding a special request and I always get prompt response.
They’re fantastic!
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.
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!!!
Good Customer Service. Fast Shipping. A+++
Our CSR for Dymax Inc., Deb, has been extremely helpful and consistently provides quick, accurate information regarding parts and inventory. When we encounter difficulties finalizing transactions through the internal website, she is able to promptly generate quotes and provide an external, secure method for payment. Her responsiveness and willingness to assist play a key role in supporting our team’s success.
Very prompt services !
Have been buying parts from them for years, and they have always delivered, both with parts and customer service.
Great customer service!
