Blinds Depot seem to have got it right.!
Review by confirmed purchaser
Ordered 4 vertical blinds and a small problem with one of the tracks. Phoned Blind depot and new track sent out immediately, no quibbles. I have since ordered 2 more vertical blinds and everything was fine. Definitely would recommend to others just on the basis of customer service. Prices very competitive too and I am very pleased now with the finished result.
