Reliance Jio Infocomm — jio gigafiber security deposit not refunded

Address:

Surat, Gujarat

I have disconnected and handed over the jio modem to jio giga fiber team many days ago and they didn't refund the security deposit till date. I have written many emails and voice complaints but there is no positive response from gigafiber team. They have made me deposit 4500INR while taking the connection saying it is fully refundable
But now customer care give random reasons and there is no positive response. Hope jio will do the needful instead of ignoring the customers
