Bad quality canvases and no customer service for complaints.

6 X A3 CANVASES received on 14/01/2025Y. When delivered I was not happy and let NetCanvas know immediately on WhatsApp. I was instructed to forward pictures of my complaints to email. I did as asked and was told they will check with factory. No feedback Till today 28/01/2025. I forward follow up emails, but get no response back. I am struggling to get these canvases sorted out. 1 Canvas was very loose - not stretched properly over frame, other 2 Canvases the images is very bad quality - (this after NetCanvas emailed me and informed my that my images is good quality). Out of 6 Canvases I only have 3 that is good to hang. Customer service is very bad for aftersales and complaint.
