Awful company! A children's rug I ordered arrived from the retailer Tic Toc dirty, the rug was meant to be sage in colour but looked brown in parts it was so dirty and the packing was all dirty. The response from the retailer was basically "its brand new and just a bit of dust"
I've washed the rug as per instructions and the dirt still won't come out, so its unusable as I'm not putting a dirty rug in my babies room. I've been onto the retailer twice since my initial complaint and have had no reply at all! Neither Fruugo nor Tic Tic will take responsibility for the faulty product I've received. Do not use this company!
