Their online service is poor!

I tried to order a dress from their website as the shop in question did not have the size and the staff apparently aren't allowed to order it in for you. After eventually finding the dress I wanted (one size up), trying to finalise order was a nightmare. It took several attempts to complete my information, the system kept jumping and deleting all the relevant info. The dress came within the scheduled time. However, although it was only 1 size up, the dress appeared to be about two sizes bigger. Trying to return it was even more difficult. This product was not allowed to be returned to a store but you could take it to a local shop that accepted the click and collect. Unfortunately the shop in question couldn't accept it, as the barcode on the label was too small and couldn't be scanned. Therefore had to go to a post office. In the meantime, I tried to order another dress. This time, the system froze both of my computers. After the 8th attempt I decided not to bother. I emailed customer services and haven't heard anything back. Not impressed at all.
