Nestaway Technologies — Irrelevant changing and cutting the security deposit

Address:

404, b wing, shiv om tower, nahar sakti, chandiwali

I checked out the property in March also from the app and paid fully the rent of that month. my moved out date on the app was the 1st of April i did received call then and did confirm my move out date and time. then I waited for 3 months to receive my security money back. during this time they closed their customer care service so I can not contact them overcall. on the app, they deleted my all payment history. in the month of April, the app was showing that I am moved out from the property but in the month of may it again started showing my account but not the payment history. then they started charging me rent; first some 1000 rs as rent then renewal of agreement 1000 rs then they changed my 1000rs rent to 5000 and some and finally when they return my security deposit it was 14907rs less. when I asked for a breakdown. they shared pdf showing April month delay money then July month rent and so on. I mean if it is not harassment then what is?
