I have discovered that trying to arrange installation through KnowHow is the most frustrating experience ever. After being put through to the wrong departments, only to eventually spend an hour holding on for and with the right department I had truly lost the will to live. Sitting listening to the awful music for over 20 minutes after the auto system told me a 6 minute wait was ridiculous. Holding on for 20 minutes for an assistant to 'speak to a manager' left me wanting to throw the phone across the room. Then holding on AGAIN for them to speak to a further department left me suicidal. Then to be told that the delivery would be put back by 2 days to arrange installation for a gas fitter to cap off the gas point left me tearing my hair out. The worst service I have ever experienced with any company and I would never go through KnowHow again. I would rather arrange someone privately. I am left absolutely drained!
