(see attachment ) The set of glasses in within 8 months scratches & not suiting my near vision .Despite repeated visits to the shop my problem stands Shop Keeper saying me Company not given any Warranty or Guaranty for Glasses . The shop keeper seems to have replaced glasses with unbranded one.I'm tired. Please sort my problem. Thanks
