Nestaway Technologies — Duplicate charges added every month.. no response from customer service

Address:

Bangalore

Nestaway is changing same item again and again in different names.
In our flat we are being charged maintenance charges (750 for 1 bkh, 1250 for 2 bhk as per bill from nestaway).
The maintenance charges includes below as per email from nestaway are manager:
1. Common area maintenance
2. Watchmen salary
3. Common area electricity bill (Water motor, common area lights, lift bill)
4. CAN water meter bill.
..
Now nestaway started charging watch man salary separately..
Also if you see the attached receipt it clearly says monthly maintenance is 1250.. but I am charged 1500..

Since nestaway completely shut down the customer care functioning.. no way to resolve it.. raising a ticket is waste of time.. no one responds to it.. I have many open issues.. pending from even 6 months back

Note: I have blurred out the personal information from the bill
