Zando refuses to fix shoes

In Nov 2015 I bought 2 pairs of wedge shoes from zando, each costing R359.00. within the first week the one pairs rubber sole started to come off which I repaired. By the end of December 2015 on both pairs of shoes, the actual wedge had detached of the top part of the shoes. I then sent them back to zando on 11 January, stating that I do not want a refund or new shoes, all I wanted to do was for them to re-glue or fix both pairs as I feel it is their responsibility to fix these defective pairs of shoes. it is now end of February and they finally came back to me telling me that they will not fix the shoes. I am extremely unsatisfied with this come back as they are expensive shoes and should last longer than 2 months. I also think it is absolutely ridiculous that they couldn't even spare a smidgen of glue to fix them. now I have to pay an extra R100 per pair to have them fixed at a shoe repair shop. In my opinion zando should not sell shoes that cost so much to only have them break in less than two month. Also the fact that they refuse to glue the shoes being that it is their defective product is also terrible customer service.
