Diamond Ring in Icmeler

Can anyone please help. We have just returned from Turkey after buying a diamond ring. We purchased the ring in The Gold in Icmeler. The guarantee certificate says the ring is VS1 in quality and F in colour. We have had a valuation done in the UK and the ring is actually SI 1 and J or K in colour. I would never have spent the money we did on this ring.
I have emailed the shop and wait a reply, what should we do. Feel so disappointed and let down.
Thanks for any help
