Query: Terrible quality

Took the bed out of the box, attached the pump as directed within 2 minutes stopped inflating and the pump began to smoke. Called Aero customer service to get a new pump since I had ordered the bed for my granddaughter to sleep in that night. Took 20 minutes on hold to get some one to answer on June 28. Their customer service could not even tell me who might carry a pump to buy locally- I am in Chicago! Everyone he mentioned was online only! Not much help for that day. Finally sent me a pump overnight! But it was not of the same quality - I had to buy rechargeable batteries and charge up. This bed is going back to Amazon and will not buy another Aero bed that does not have a pump built in.
