The 1st thing I asked when we were at the American swiss store is if they will be bale to resize and the lady assisting us said they will.<br> I bought Lay bye *** ring *** for R14999.00 and and laybye *** ring *** for R3999.00on the same date.<br> I paid R6500.00 &amp; R500 on 20 Nov 2015<br> I paid R2000.00 &amp; R800 on 28 Dec 2015<br> I paid R6499.00 &amp; R2699.00 on 02 Feb 2016 which was the remaining balance on both<br> At that point was I advised that they wont be able to resize. they were going to make a special order and I must take the ring home in in an N and I am a V and half. I refused to take the ring not in my size as I was never told that they wont be able to resize<br> I called the store twice between 02 Feb and 10 Feb to enquire on my special order, and I was advised at 18h50 on 10 Feb that the supplier doesn't make that ring anmore and I must choose something on the floor. Both rings are still at the store and I would like my full refund back of R18998.00 as I'm getting married on 27 Feb 2016
