Jiomart — Tampered product delivered and full refund not issued

I have purchased a Loreal shampoo worth rs. 254 for 396 ml on 19th March 2023. However, the product delivered to me on 20th March 2023 was tampered. (Attached pic). And also, the quantity was of 340ml.
I was promised two times by the customer service executive from jio mart to pay for full refund, however the full refund of my money has still not happenedtill date 27th March 2023.
This is just a mental torture by jiomart
