No refund for broken handbag

I bought a Paolo Rossi leather handbag on the 1st of April from this shop for R1214.96. Within the first couple of times I used it the shoulder strap looked like it was about to come loose and the leather on the top of handbag and on the straps started scuffing. The closing mechanisms also gave problems as it was 'winding' out and had to be moved back every time. When I returned the bag on the 1st of May 2015, I was told that they will send it to the supplier and I will have to deal with the supplier. That is their policy (which they did not tell me about when I bought the bag). I do not want this bag to be fixed (what will I do if the strap breaks off completely?), I do not want this bag back, I want a refund to buy a different bag. I also do not want to deal with the supplier. I did not buy the bag from the supplier I bought the bag from En Route. Not good customer service at all. When I returned a second time to see the owner, none of the ladies tried to assist me to track him down and I had to concede and let the bag be sent back to the supplier. Their motto is 'where service never takes a holiday' - well their service is on another planet as it is non existing.
