Don't use this company if you want your curtains to fit!!

After patiently waiting for 4 months for my curtains . . when they arrived they are too short. I have waited to see if they drop, they haven't! Customer services tell me that they have a tolerance of 2.5cm, I don't!! I would have liked my curtains to be the length I ordered They are 1cm short and have been hanging for several weeks now without any change to that fact! As they are for a bay window and need to 'sit' on the windowsill, I have spent a lot of money for curtains that look dreadful.
