Bed linen - Terrible quality

I purchased bed linen from Volpes. After a week's use, the pillowcases have unexplained bleach stains, getting worse each day. The duvet set, which was R1299 ( a premium price in my opinion), has terrible stitching. There are bunches of threads all over, and some thread has already started to unravel. If this is how the duvet set is looking after a week's use, I don't think it will last even 3 months.

I've sent Volpes an email to info@volpes.co.za without any response. Hence, why I am now posting this review publicly.

Please let me know how I can contact them.
