Lenskart — Power eyewear

I bought a power yellow hustle eyewear on March 5 from ernakulam. During the purchase the staff checked my power if it's changed or not as i was already using a eyewear. as there was no change they issued me the glass even after knowing that my one eye has power of more than 2. They did not informed me or the person who accompanied me before buying the eyewear that it will get loose or it cannot be adjusted .it was an irresponsible behaviour from the staff. As i am person who is using the glasses for more than 15 years . Hustle eyewear has certain limitations is not informed to the customer. I experienced it in two shops.
