American Swiss runs ********* business practices!

I am APPALLED and INFURIATED, by the ********* business practices of American Swiss. I purchased a TEMPO Active Watch from the jewellery store (in Richards Bay), but had constant issues with the device and took it to the Empangeni branch two months later, to which I was notified that the device was INDEED faulty and they would be issuing me with a new one. Before, going to the store, I called to find out if everything is good to go, in order for me to collect my watch, to which the consultant rep**** yes! Upon arrival, I was told that because the item was on sale when I bought it (the item was R999 to which I received a 50% discount on my account and only paid R500) I would only be covered for R500 and would have to pay the balance. Did I make the faulty watch? Is it my fault TGF decided to run a 25% off promotion on all TEMPO items that month and I was due a 25% discount on my next purchase? I had never heard of such nonsense before, I then asked for the amount to be credited to my account because I would not pay R500 cash in order to get another watch. Once credited because of interest rates and all that jazz only R264 was returned! The whole experience was such, an inconvenience because I could have taken my business elsewhere, my watch was in repairs for over a month just to be told some BS!!!!!!!!!!!!!!!!
