Wangjinqi review: multifunctional effervescent spray cleaner

I ordered 50 pcs of above item. Received item after almost a month. It did not work even using 5 tablets, no effect at all. I sent email to return it but responding back with same type of response over and over, like a broken record. Finally she wants me to settle for 20% return of my money plus positive feedback. When I emailed back the email add was no longer reachable. It was a rip off. I looked up "Axtonstyle"on the internet (name shown on the receipt) it shows the name of the company in England., which is Qandies Limited. I sent message on the contact email add but did not have any reply. The phone no. is 852-[protected]; address - Liaoningsheng shengyangshi shenhequ beizhan, Road No. 72, Shen Yang Shi, Liaoning 110013 (as written on packet). I want even half of my money back because shipping it back to them is so expensive. I think that's the catch.
