3rd time this is horrific and really poor

my horrific experience started in Jan 2017 when i purchased a ring from the Pivillion branch in DBN, the sales person who had sold me the ring, said that i would be able to resize it, all i would need to do it take it to my nearest branch. Upon taking it to the phoenix plaza branch i was told that the ring could not be resized(March 2017), eventually i had to chose a new ring, I had the ring for a month (April 2017) or so only to find out that the stones on the ring are moving out of place, sent in in for repairs(May/June), i was then told that i will be receiving a brand new ring, low and behold i find that the stones are still moving. the ring is currently at the phoenix store. i am really disappointed by the pathetic poor service i had gotten, I WANT MY MONEY BACK. really sad, so many attempts and still cant get this right.
