Lenskart — Damaged and destroyed my frame

I went to lens kart Kalyan nagar to repair my specs ( issue in the specs it's 2 months old and it become very losse for me and one is new specs and other one i have changed the lens). One execute went to to repair and he brought the specs more wide and he damaged the side support. And he said he will discuss with his supervisor and he took 20 min to return saying that his supervisor having food. And supervisor came after 30 min and she said we can't do anything and i told them to tight the side support and give. She said okay and she said it will take 10 to 15 min. So me and wife went for dinner for 30 min and came back. One specs they made okay and other specs is still not fitted and i said that to excutive.. his response is that's it we can't do anything and i got anger and asked give me the specs how i given to you. Then he went to repair and took 15 min

He is very smart that he changes the side support of other specs and connected to my specs.do you guys think iam a fool.
