Symphony Limited — Want to replace with other model

Hi Team,

I had purchased cooler on 28-May-2021 (received date) below are the order details:

Order no : SYM[protected]
Model Number: Symphony Diet 3D 20i Tower Air Cooler 20-litres with Magnetic Remote

I assume it is coming in good height (As per product image it is looking enough tall but it is not that much) and as per product detail it is enough to cool 13mtr2 room but when I tried it in my bedroom which is 10x10 feet i.e. 10 mtr2 it is not cooling this area.

Now I would like to replace this cooler with 35ltr capacity cooler of the same model to get desired cooling.

Please help me to get it resolved very soon.

Regards
