Solarplexius - Order pt31203- doesn't fit and injured myself

Order PT31203
I bought two side shades for the rear seat windows from solarplexius for my Peugeot 308 SW from 2009 and they don't fit, they are way too big, I tried for almost two hours to fit them into the side windows and only damaged my car and injured myself when solarplexius says on 15 minutes they are installed.
I believe this is my biggest disappointment from an online purchase.
I hope I will get my money back, I am Available to send them back to get a 100% money Refund and to take back this complaint or to trow them into garbage and let the complaint online.
