Bajajfinserv — home loan

I have raised a request for foreclosure letter almost a month ago, till now no one responded, even i dropped customer support head thsley also not responding, went to localbajaj branch there is no proper response and told. Me to drop mail to [protected]@bajajfinserv.in, sent multiple emails but no response
Not sure why bajaj is torturing customers like this without responding??

While loan processing showed personal interest and kept on calling for leads. Now they are not bothered about customers

Am really tired asking foreclosure letter, really fed-up with their support, worst bank i did a mistake by selecting bajaj

If anyone there, please help me
