Has anybody had any experience with Ecostar ? I have found them a little difficlu to deal with only geting back to me once every 3rd time I correspond with them. I am after a single window to be changed and if I am satisfied with the result will look at changing another 4. So far their price done over the phone was good but they have been difficult to deal with. I udnderstand I am ot a potential priority customer a my job is small however may look at paying extra and going with Nu Eco who have been very helpfull although significantly more expensive.
