Leaky, crooked gutters

Installed custom made gutters. All seams leaked. Used 1/4 inch screws to hold gutter to house. Down spouts came off in first wind. Gutters did not drain. Would not come back and fix, even thou he promised to come out every time I called. Had to have another company come and take all gutters down and install new ones as the gutters were not installed correctly and the water ran back into the house, under the shingle edge. BEWARE as the comapny that we hired to redo this mess said he had been called to fix a lot of gutters installed by East Carolina Seamless gutters.
