I purchased jewellery from Giva.com and the certificate of authenticity was not there. I have complained several times and they agree it is a mistake from their end but refuse to provide any certificate as shipping will cost them and they dont want to get into that trouble. Can someone please help with that. Order id GI[protected]...
