Poor courier service

I ordered something from Fruugo for R770 including courier fees. It arrived and was faulty. Now fruugo wants nothing to do with the return as Like they say they are just the logistics company and I must take it up with supplier. The supplier wants me to ship it back to them that will cost me over R1000. This means I pay more than double to have this rectified. Don’t work through Fruugo as this will cost you more money than you expect. I feel if fruugo delivers they should handle returns on supplier expenses. It’s their fault it’s broken. Why should I pay.
