Windows installed. Noise horrendous from outside. Large gap visible in frame from indoors to outdoors. Very rushed engineer moved glass etc. Said was done. Noise still horrendous. He tried to blame normal road noise. Can hear people talking, whistling, even heard someone on phone and could hear the person on the other end of line!!!! Emailed several times. No response. Only response to say I have no authority as in partners name. We jointly ordered and paid so why? Blatantly sexist. This has been since July. Appalling service. Fitters were amazing. But clearly an issue with production, customer care, management and communication.
