Nestaway Technologies — no payment of electricity and maintenance bills

I have given my house to nestaway on rent but nestaway is not clearing the pending electricity and society maintenance bills since many months.

I have raised the tickets in their system for the same and escalated the same to level4 which is the last level of escalation but even after follow up since many months they are not clearing the pending bills.

Following nestaway employees are involved in the tickets and they are fooling me by their false promises...
Mr. Vinod (Nestaway)
Ms. Pinky (Nestaway)
Ms. Kasturima (Nestway)

Please help!!!
