GREEN-******!!! THE WORSE STORE WITH BAD QUALITY AND SERVICE!!!

I bought a pair of Jana sandals from Pavilion KZN on 15 March and when I wanted to wear them on the 16th I realized that the right foot's shoe had a defect and made a clacking sound when walking. I immediately took it off and took it back to the shop the next day where I asked for an exchange. The lady at the counter checked and they had another size 6 but the manager refused to exchange it and told me it could be the sticker at the bottom of the shoe which caused the sound. She took the sticker off and send me home to try it again and see if the sound was still there as we couldn't hear anything in the shop because of the extreme noise in the mall. On my arrival back home I again tried the shoes and the sound was still there, depending on how I put my foot down. I also asked my husband to listen and he also could hear it. I then send an email to Greencross and they advise me to send photos of the shoes, the box and the slip which I did but it didn't end there. Thwy then again send an email and asked for my number to contact me. After our discussion they told me that they will revert back and when they did, after a few days, they told me to take the shoes back to the shop (which is not just around the corner as I don't reside in Westville where the shop is) from where it will be couriered to Jhb for assessment. They couldn't give me a turn around time and it has been more than 2 weeks since a bought the shoes already. How long do they expect me to be without shoes, which I paid R1000 for and which have a defect? Why do they think I would ask for an exchange of the veey same shoe if there was nothing wrong with it? I find this totally unacceptable. This is the worst store I ever dealt with... BAD QUALITY AND SERVICE!!!!
