Kays Jewelry Signet Jewelers charged us for work they couldn't do correctly san bernardino ca

After checking her ring size a total of 3 x's before submitting the order, Kays Jewlers  in Inland Center Mall, still couldn't get the right size. They charged my 89 yr old mom $390.00,  and  refused to correct their mistake, unless we paid them another $390.00. When I took the rings to another jeweler he showed us other required repairs that which were never even mentioned  to us. There is no way we should have to pay for a sizing they couldn't even get right. Plus they should have to stand behind their work, and refund the charge.
