Poor online shop

I attempted to purchase three curtains in July via the online shop. Only two got delivered in separate parcels and the third got mysteriously cancelled - which did not help as the space required three curtains. I then attempted to arrange for collection - which took the better part of a month to eventually arrange. However, although two curtains were returned, they only processed a refund for 1. Another two months have passed with various email follow ups and phone calls, and still no refund. Their online store is not up to standard and not functional as there seems to be no recon on stock in and out. Won't shop online with them again.
