Inferior product and bad after-sales service

Purchased a Guess watch from Galaxy & Co Eastgate. Had to return it 4 times due to faulty mechanism and screen fogging up. Received a new watch, same issues recurred, and in stead of offering me a refund, as requested today( because this is the 5th time the watch needs to be repaired within a period of 3 years), I got bad service from the store. The watch needs to be repaired, yet again and Galaxy needs to start taking responsibility for this now, considering that they are selling a product of inferior quality, which is not my problem ( I know of another who is experiencing the same issues with Guess and I definitely no longer want this watch--also, the warranty expires this year, so there is no recourse for me if anything happens). Also, the store manager was very unhelpful and rude towards me, even after I said I would complain about the service. This is the last time I will purchase Guess or purchase from Galaxy & Co.
