Reliance Jio Infocomm — Non Refund of Sec. Deposit

I had surrendered my Jio Fibre connection in January 2022. The Router and Set top box was also taken back by the co. 0n 26th January. A new connection was installed next day.

The guy who installed the new connection did not hand over the adopter for set top box (he felt the old one will work as well). The company have deducted R225 towards the cost of adopter.
This person has subsequently handed over the adopter to me after I made several phone calls to him.

I have ben requesting the REL JIO to take back the adopter as it is of no use to me and refund the deducted amount.
There has been no response.
