Ring has been repaired three times 10 months

My name is Thobeka Luthuli(Sibisi) I purchased my ring on the 05 of August my ring was resized to Q and half, The ring became faulty the first time around December and was repair, I advised that I was not happy with the ring but told that the warranty is new after every repair, I than went to my second repair on the 04 of March and no one I complained again but NO ONE TOOK ME SERIOUSLY, I work at Samsung and understand the CPA process clearly but I was misled by one of you OWN agent, My ring just went for third repair in LESS THAN A YEAR on this month , It came back last week Friday and the diamond is out again, I AM VERY ANGRY AND DEMAND YOU DO SOMETHING ABOUT THIS!!My ring is not even a year old.

My number is ********** 376 **********
