Boat — Replacement not done properly

Hi Team,

There is an issue here. My power bank has been replaced but it is only cell capacity of 10000 mAh. But actually my power bank was of 20000 mAh what I have returned to you. So, why the product has been replaced with very less cell capacity? I want the power bank what I had purchased, the same model and the same power. I want the replacement of same model which I purchased. The model is ( 20000 mAh Energy Shroom PB-18).

Kindly revert asap.

Waiting for your reply urgently.
