Crizal — cheating in happy offer by crizal

Address:

40, Gangadhar Society, Hansol, Ahmedabad, Gujarat, 382475

I changed my old crizal lenses with newly purchased crizal lenses on 8.09.2019 and i asked for happy offer by crizal to the vendor and ask to provide one free lens set. The vendor told me that he will arrange an extra pair shortly. Then i tried to contact many times but told me that he will update soon. Now today he told me that this offer is valid only for new purchase with frame...
But i told him that crizal provides only lenses so offer should be applicable on lenses only.

Please look into this matter
