Galgotias University — Not refunding the fees

I took admission in galgotias University under Bsc (forensic science) course during may 2019 but immediately due to personal reasons I opted out from the course. I submitted my application during the admission time and they also accepted it and assured me that I will get my fee refund till December. When I got no phone call from them regarding fees refund, I tried to contact them but no one heard my complain and either everyone just keep transferring to different departments or keep giving me wrong numbers. I also visited them but they still just assured me that till December 2020 I will get my refund using covid-19 as a reason for not getting my refund. I still haven't got my refund and they are also not picking up my calls. Kindly help me with this situation.
