Poor Quality

I would like to express my disappointment with Sterns. I purchased a Minx watch in May 2015. After just 3 months the strap came loose. I took the watch back on Saturday because I wasn't around in Gauteng. I was assisted by Kgaugelo Ma*****e which I receive no apology from and she just said okay to everything I said. Finally she advised me they will send it in and most probably glue the strap. # glue I was so surprised. They booked it in for repairs. I'm very disappointed in this poor quality that is being sold nowadays. I have been purchasing most of my jewellery at Sterns and this is the first time this happens. I will take this matter further. I will not accept that watch back. As a consumer I want a refund or a replacement . That watch is clearly a factory default . I have a current Minx watch that I've been using for 6 years and its still in good working condition. As stated I want a refund or replacement watch and will not settle for anything less.
