Lenskart — I didn't receive the order and I paid already

Address:

Bangalore, Karnataka, 560074

I ordered colored lens at 5 of september from lenskart showroom in gopalan arcade mall banglore.. He asked me to pay full amount and i paid.. It was 723 including tax.. He said i il receive the order by max 12september... Today i called and asked and he was telling i already received the order... It's really irritating. I didn't receive the order atleast give my money back
