    The Double Order Catastrophe
    My co-worker placed an order and wasn't sure it went through online. I later placed the same order thinking the previous order didn't go through. To my surprise both orders went through, and I needed to cancel one of the orders. I called and spoke with someone who instructed me someone would contact me about the situation. I was contacted by Misty and she said she would do her best to cancel one of the orders but not sure if she could because they were next day orders. A small tome later I received an email saying she was able to cancel one of the orders. Thank you to Misty and the entire Propel Parts Team. Greatly appreciated!!

    A Delay Handled the Right Way
    Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.

    Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.

    Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

    P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you.

    Very helpful. Every question or request I had was answered quickly. I didn't have a parts book for my excavator but that was no problem for them. If you need parts for your Cat, give them a shot.
