Jio Fibre services pvt ltd - Jio Fibre Refund amount not being paid

Hello Team, I have take Jio Fiber connection on Feb * ****, via sales executive giving me wrong explanation/half information that you will get access to all OTT and *** channels, Upon connection we realized that all the channels were linked to ott apps which use to work properly only when there is good signal in Wi-Fi strength. Frustrated with this I have cancelled the Jio fiber connection on Feb ** ****. The service SLA for refund is ** days as per policy however its been more than ** days i am struggling to get my refund. Issue being the executive when visited for asset collection has entered my bank account number incorrectly( which I got know after ** days after talking to customer support team, Since them I am writing emails to update details to which they are not updating details and replying same comments that you will get refund and further action, A link sent to update bank details also doesn't work as the error says refund not applicable "which is also mentioned in their company message that in such state please contact Jio fiber. Since then it is ** days I am asking them to call back and they are not calling and not updating details not refunding my amount. From the beginning of the service these guys have given fake promises and harasser me by coming home every two hours to take connection and now not even responding when refund needs to be given.
