"Ripped off by this platform and their seller"on 22 Dec 2020, I ordered the following through their selling platform
Puma California Casual Mens Black Leather Lifestyle Sneakers Shoes Size: US 9,I paid GBP 59.00
All I got was tracking links, still don't have my parcel , because of Fruugos , "terrible customer service" which in my experience , of which they have no concern for their customers, now I am being ignored, because if I have tracking links and not my parcel,, it's my issue .., feel ripped off by the seller and by this platform, I will not give up, they wanted me to be a private in investigator for them, I did even , thinking it was my issue try and get in contact with UK customs , DHL ecommerece, Yodel , DHL parcel , even DHL eCommerce , had sent, many phone phone calls, emails and chatting with online support to all of these companies carrier companies, and back and forth with Fruugo , thinking it was my issue with all these carriers , companies who all advised they needed waybill/shipping code , which the seller couldn't provide to me, and even DHL eCommerce advised to get the seller to register a lost parcel claim which they are simply ignoring, even worse I got Fruugo customer (non) service to try and help but they are not interested in customer rights and now ignoring me, which is criminal .., this is by far the worse online and customer service I have ever experienced and embarrassed this is a UK based company.., trading standards I'm in the process of contacting as they have broke my consumer rights
