Having enjoyed 4 years of top class service from Air Products I have to say my first experience of dealing with Air Liquide is that the transition is chaotic. I've basically just spent 2 days housebound due to their ineptitude. I ordered 2 replacement cylinders plus a new tube for my concentrator last Friday and after 4 calls and numerous unfulfilled promises of call-backs I've just received my cylinders which were promised for yesterday-there were no orders on the delivery for the tubing. I've missed a hospital appointment and been fobbed off and have concluded that their customer "service" is unfit for purpose. My delivery technician confirmed this and apologised profusely. I bet there's somebody high up in the NHS or government who's patting himself on the back for saving a few quid. We were promised an improved service; we have been lied to. Welcome to Camerons' NHS 2012 - it's safe in their hands?
