Will not receive items for Xmas, false advertising on delivery

End of November I ordered two bracelets as Xmas gifts from them. When I ordered they stated 5-10 working days to deliver. So based on that I ordered two with the hope of getting them mid December, in time for Xmas. Time has run out and when I asked where is the bracelets, they say it will now take 10-20 workdays to deliver... Putting it way after Xmas. Now I have to buy two other bracelets from someone else, only to have something as gifts for my girls at Xmas. This is false advertising and will not make use of them again.
