Breda Contracts

i am not happy with this group i have paid them in full for work done in my house. There are so many things wrong with it. i have talked to the team leader Gerard all i get one excuse or blame after the other. i never delayed in paying them. The double glazed window the put last summer is not active in two areas of my house, my heating in the bathroom is leaking i have called to explain he promised to come it is now going 4weeks no show. My conservatory is leaking he blame it on my wall,
the new bathroom i paid do not run i have to use the bucket to shower he blame it on my water level. But he is they one who went out to buy and over before work started. Ii has resulted to emailing has i can not contact him in any way. Can some help me tell him to come and fix the work and also bring my receipt or would leave me with no choice but take action? Am totally fed up with one excuse after another why does he take me for a fool now to make matters worst he has taken his Facebook contact off and the number i have and my friends who recommended him is not going through. Further, they alone know what the did with my electric i have to call an electrician out to come and look after i have bought two whole house appliance thinking that something was wrong. Whatever way the did the pull a cable left the other socket not working, and both cables were life. Please, i need your organisation to look into this i am fed up.
