Resize

after going into a nwj store i was told i will be charged for a resize as i do not have the reciept. the lady didnt seem to understand that the ring was purchased +-3.5 years ago in kzn and we have moved 3 times since then. she also didnt want to advise on whetheror not i could get a valuation certificate on the ring as i required one. i do not see how asking for something afte paying thousands for a ring is so difficult. its not like they cant see the \newness"of the ring nor their stamp. i just want to make sure the type of ring i give for resize is the same carrots etc that i get back. nothing major. she then went on to tell me resizing is free but for me its not. why? i certainly have stopped supping this store."""
