Poor service and low quality products

I bought glasses at the Fourways crossing branch, firstly I had to physically go there to find out if my glasses are ready, no communication was sent to me. Secondly within the first month of having these Prada frames the colour on the frame started chipping. I went to the store to get this resolved and at first they accused me of damaging them even though I took good care of them and they were always in their case, then eventually a lady assisted me and took pictures to sent to their supplier and told me she would have feedback within a few days. Two weeks late I went back as the chipping of the frame was worse, when I followed up on feedback from the service provider I was told no query was send, a whole two weeks late, to say that I am disappointed is an understatement. Then I spent almost an hour waiting as they going through the process of taking pictures to send to the supplier and looking for a frame that I could use in the interim. No suitable frame was found so I went home with the same tarnished frame, I was told that the case has been handed over to the manager and they would get back to me, that deadline has come and passed and I am still waiting. The worst service and on top of that their products are of a poor quality.
