Frustrating Watch situation

On the 24th of November 2017, on Black Friday I bought a watch at Folli Follie in Canal Walk, I was so excited about the watch that I put it on immediately. They put it on time for me but later when I arrived at my hotel, I thought it was a bit behind. I kept putting it back on time because I thought it must have been the battery. The first thing when I arrived back home, I took it to my local jeweler who put the new battery for me, but the watch continued to be behind; the following week I called FolliFollie, I sent them proof of purchase and they told me to take in to sandton which is 4hours away from me(I live 12hours away from Cape Town).

It's been a month, my watch is still away, I went to sandton and they are just telling me that they don't know, I spoke to the manager in FolliFollie canal walk about two weeks ago, on whatsApp asking her to please assist because I'm worried now about this watch situation. Her short response was "will do". Up to date, it's quite... Over R1700.00 gone, no watch, no message, frustrated...

I don't know what else to do...
