Flawed product and poor customer service

I heard carpets fitted on 30 August through 4 rooms and my passage; Although we had been asked to pay up front to ensure a consistent die a lot every room is a slightly different shade One carpet is flecked with black specks and looks moth- eaten; It has taken over three weeks and the situation has still not been resolved Both the sales consultant and the supplier seem to be intent on trying to bully me into accepting an unacceptable situation I have made repeated respectful and courteous requests ... still hanging! Very poor customer relations They “hear me” but have done nothing to resolve the problem
