Query: Dead on arrival, good customer service

Not much to say, the jack was heavier than expected but it is good looking and fairly easy to move around. I does not work !! I have followed the procedure to remove air and checked the oil level. The jack does not raise at all. Called customer service and left message. Will update as the case progresses. Customer service called back, and gave me a procedure to follow, the procedure made sense, but unfortunately did not fix my jack. Called customer service, left message, they immediately called back and offered to send me a new pump. Exellent solution. Will update when pump arrives.
