Not sure I feel scammed on my free earrings purchase with engagement ring because the back falls off too big. CUSTOMER service not helpful just said they are sterling silver and won't replace! But can't wear or I'll loose them. You pretend they are a 700.00 value so I would appreciate a replacement free pair of round studs as often as I've purchased from you. Please consider this as my backs the hole is too wide to secure earrings on promotional studs. The customer service was like too bad try silicone piece. That won't help!
