I had trouble with customer services when returning a faulty blind. I was as refused several times before checking my legal rights regarding online purchases after which I returned the faulty item and they covered they cost of postage. After which, I reordered a blind from them that was not faulty and which fits the window and is of good quality. The blinds are good value as well. However their returns policy needs to be reviewed in line with online purchasing rights in the UK. (these were not made to measure blinds but standard sizes for velux style windows).
