Got trapped by Lenskart Exchange policy

This is the first time i have ordered something from Lenskart. As a new customer i did not knew much about Lenskart products and exchange policy.

First of all i selected a frame worth ₹1500 and lense worth ₹1200 and submitted my prescription for lense power, my cart value was ₹2700 and after applying discount i got final price of ₹1500.

I received my order but the frame was but smaller for my face so i thought to exchange it with another size frame with same lense.

when i applied for exchange i got option to choose from selected,limited frames.(here the trap starts).

I choose a frame from lenskart blu computarised lense (i did not knew that these frames come with 0 zero power glasses. ), when I selected this frame it asked me to select lense, when i clicked on it, it directly showed the payment page so i thought it might have automatically selected the lense and power from my previously ordered frame. ( here lenskart should have showed me confirmation message asking me if i really wanted to exchange powered glasses with zero power glasses [ but then how will they trap customers ])

When i received this exchanged frame i got to know that it has 0 power glasses and this same frame and glass without power is available for ₹600 on Lenskart itself after applying discount.

So again i thought of placing exchange order and went on to carefully select a frame that comes with powered glass.

Whichever frame that had powered glass option was showing additional ₹500 after exchange so that the total price will be ₹2000.

i did not wanted to pay more ₹500 so instead i choose to cancel the exchange order and keep the frame (one with zero power) that i received.

Zero power glasses are also comfortable for me as my both eye lense power is - 0.50, which is very minimum.

But i am really disappointed by the fact that i got trapped to buy ₹600 worth specs for ₹1500 on Lenskart.

Will never ever order online from Lenskart and also wont recommend anyone to buy online from Lenskart.
