Sorry Philippa Evans to hear about your bitter experiences and disappointment in dealing with a jewelry store in Sri Lanka. Wonder if the store is accredited by the National Gem Jewellery Authority of Sri Lanka, the body that oversees the Gem Jewelry trade in Sri Lanka. If so, you could lay a complaint with them about the shabby treatment meted out to you by this dealer. Their contact address according to their website is No.25, Galle Face Terrace, Colombo 3, Sri Lanka. Alternatively, you may go to their website and open their contact us page and lay your complaint in the cage meant for Enquiry.

You can also try to contact them over the phone numbers given in this page. Good Luck and God Bless you !!
