An engagement is suppose to be something exciting and a new chapter of 2 peoples life. on the 12th June we went to American Swiss Carnival Mall my partner walked out before he said something he should not. i went to American Swiss to find an engagement ring - instead i was treated like well if you don't like what i say then tough. i have a size U ring finger so for me to buy a ring i need to take in consideration the cost of the ring plus the ring to be resized, i stated clearly i dont want the ring stretched and would like to have an extra shank put in so the ring does not lose it strength and shape. "i was told well if you like then you must pay the extra what ever it is." all i need to know how much is it going to cost to have a extra shank put in the ring - another American Swiss said R3000 thumb suck could be more which i dont see how if a few other Jewelry shops have been under a R1000. so i asked the question do they know as i did see i ring which i liked and would purchase but need to know the added extra. the response is " yes thats what is cost : i was told well if you like then you must pay the extra what ever it is" so it comes down to who cares if we make a sale or not. all i wanted to know if they could get a quote on having the ring sized correctly. i must first purchase the ring before they do anything and yes i asked if it is to expensive to resize the ring what then do i get a full refund "oh im not sure" was an answer. the service was terrible left the shop totally unhappy - they did not even tried to help me as a customer. the price tag of the ring should not matter its about service. will now take my business to another jeweler at least when i asked for quotes they help and made me feel excited about purchasing a ring.
