Diabolical Customer Service

Had composite door and guttering fitted May 2015, started having problems straight away. After call after calls and visits to the service department, eventually we received visits from numerous engineers/surveyors and fitters, however problems with the door continued. Hopefully this has now been resolved after 11 months. My utter disgust goes to the service department, we've had no apologies, no phone calls asking if there was anything they could do, or if the problem has been resolved, nothing. Even emails and written letters to the MD went unanswered. What company does not have a complaints procedure G2S don't. And yet they have this statement on their website...
(At G2S, we are a family run business who pride ourselves on our integrity, offering you an honest and transparent service you can rely on. We employ over 50 highly trained staff dedicated to providing you with the best possible knowledge and CUSTOMER SERVICE – INCLUDING A FULLY MANED SERVICE DEPARTMENT).

That is the Understatement of the year. Word of mouth goes a long way as I'm sure they know, but it will not happen here.
