"I ordered 2 auto parts a thermostat and a water pump the shipping was 17 dollars, I wanted to add to the order but could not find a way to do that, keep in mind this all happened within 15 min from my first order. I decided to cancel the order and then my plan was to reorder and have the three items sent rather then being hit with another delivery fee. I was only allows to cancel the water pump and not the thermostat, so the thermostat was around 12 dollars with a 17 dollars delivery fee, I would much rather cancel the thermostat and revive the water pump for the cost of the delivery. So there was no way to communicate with them as they do not have anyway to reiterate any concerns or changes to an order. They have lost my business I ordered the water pump and the serpentine belt from Amazon and will continue to do all my business not with Rockjabber LOL. They lost my business."
