Airtel — Refund status of disconnected broadband connection

Hi Airtel! I had taken an year long plan of airtel broadband[protected]_dsl in indore in August 2020. Due to unforeseen circumstances, I had to shift to jodhpur in November 2020. I had raised a request to shift my connection to jodhpur but it was not available as confirmed by airtel team. They told me the refund amount of around Rs 7500 will be processed in 45 days. It has been more then 60 days but there has been no refund or update of any sort. I hoped airtel service would be much better as compared to jio but the experience has been pathetic. Please let me know what I need to do to get the refund asap.
