Reliance Jio — No Refund yet credited back as was promised during disconnection

Address:

Bangalore,Karnataka

During the installation on 15th September 2020 the Jio team charged me 1500 rupees as a security deposit in accordance with the installation policy. After the installation I asked the team if there were any hidden charges or any extras that needs to be paid. They refused to accept any amount and addressed their policy of refunding this security deposit back as soon as the device is returned to them. There's no extra charges required as per the company's policy. But they need a tip amount and that too convincing. Pay everytime for your use accordingly. After all its a prepaid connection not postpaid like BSNL. There's been not even a single month has passed that the fiber has worked without the technician visiting to do some adjustments almost every single month. And here also everytime any tip amount according to your convenience. Now I had to return back to my hometown after completion of my college. So I submitted the set-top box on 26th August and got the fiber connection disconnected coz it won't be of any use. This process was quite quick. The disconnection and the collection of the box was really quick i.e. within 2 days though it was mentioned it can take upto a week after the submission of the request. There were no circumstances faced here. But the person whom I had to call for the cancellation procedure gave a good idea about company's way of attracting customers and then telling them the truth. They will be charging 1000 Rupees for the convenience and installation fees which their company's policy restricts them from doing as mentioned before during installation. Now what about the other 500 rupees if they feel convinced with the return device they will think about it. They will think about my security deposit and that too after taking the set-top box back and checking its condition in front of me while it was connected. I have no idea what extra steps they needs to be taken to ensure the proper working of the set-top box in their office. Its almost 17 days now. No mails/no refund yet been credited. They have also taken my bank details just for the protocol. There's no way one can contact the Jio services regarding cancellation/refund. As there is no such policy available in their platform. Whenever one visits Jio's Platform there's everything starting from booking a new connection to doing recharge. But there's no option to check for cancellation status/request/refund status. Service id, order number are provided but no place to enquire against them and no way of calling the customer care as no department is concerned with cancellation/ refund, no such option exists, everyone is interested in having new customers to avail their services. Hope I am able to elaborate my issue here. For any further requirements/query from your end I'm always available at [protected]/[protected]@gmail.com.
Please look into the issue and suggest an appropriate action if necessary.
Thank You
