Plumbing Force review: Scam scam scam

I booked for an engineer and pre paid £144 as my boiler broke down and was leaking and they said that most jobs were fixed first time as all their engineers carry the parts required to fix.
The engineer turned up and didn't even touch the boiler and said that Plumbing Force would be in touch with an estimate. I waited a few days and didn't receive a quote - so I booked for the manufacturer to come out and take a look which cost a little more - their engineer to two minuets and worked out that it was just a blocked drain pipe that was blocked - also threw in a free service.
I chased Pluming Force as still nothing - eventually I found their quote in my junk mail saying that I needed a new sum seal (which I didn't) and a service and quoted me £1170 on top of the £144 already paid.
I questioned this and got nowhere!
Be very careful parting with your money to this company and don't trust them - if I can help someone else being scammed by this company - I will have done well.
