Tata Housing Development — Electricity Meter /Submeter not being provided to us even after purchasing.

Address:

Tata Avenida, Newtown, Action Area 2

Worst Experience purchasing property here. I recently purchased a ready to move flat and first there were so many delays at tata's end getting the approvals and all, and now they are not providing us with the meters, harassing us, giving meter to people who applied later than us, and saying baseless statements that "no stock available" for the last two month. JLL is the worst group and please prevent yourself from buying or investing at TATA at any cost. Because once you purchase the flats worth 1 crore and above, you cannot turn back and will be harassed by them with their baseless custom service, and useless rules and regulations.
I am not even sure whom do I contact for meter connection, as there are non responsive, and on top of that they are charging for the maintenance.
