DISSATISFIED CUSTOMER in North York

I had window coverings installed at the end of October 2017. They were a bit too wide as 3 of them, side by side, were overlapping each other and would knock into each other whenever they were opened/closed. I complained about this immediately and was told it would be looked after, i.e. someone would come in to adjust or replace them. It is now the end of FEBRUARY 2018 and they STILL HAVEN'T COME TO REPLACE/ADJUST/LOOK AT IT!!!! I have called Home Depot Customer Care Services 3X, talked to their Escalation Dept 2X, spoke to someone from their Installation Services Head Office 2X and TEXTED THE CRAP OUT OF THE INSTALLER....STILL NOTHING!!!!! DO NOT use this company if you want quality, efficiency and compentence with your service.
