Uwinshair lnvisible Lace very Visible

I ordered a womans month special 3 wigs. The 2wigs are fine. But my 3rd most expensive, HD invisible Lace wig is Very terribly visible! The lace is still visible even after having my hair plaited, got the wig lace cut and fitted at the salon. Lace still very uglyly visible. The lace is even looking bad compared to the other 2 normal lace wigs. I made contact with Uwinshair, all they say is the below:

""Hi dear, Thanks for your order. I have checked that you have cut the lace,and we are willing to give you 15$ as a discount coupon for your next order. Please kindly let me know your ideas.""

How dare you!? I didn't get what l paid for. Such a RIP-Off!! Terrible after sales n no integrity at all
