Telangana Southern Power Distribution Company [TSSPDCL] — Linemen disconnected power supply line without written notice

Address:

champapet, Near TKR college.

I already have a domestic meter connection for my one room house, Which I had to demolish due to structural instability. I'm now constructing G+1 house which is 95% completed.

Linemen had disconnected my domestic meter connection back in December without any written notice when asked he stating G+1 residential house construction as commercial activity and I needed to switch billing of my existing meter from domestic to commercial billing. Also asked to apply for new 3 phase meter and took cash to restore power supply.

Now he is back asking to switch both the meters billing from domestic to commercial billing as construction is still in progress laying tandur stones hand cutting, We do not use any heavy equipment's only tool we used so far is TILEs cutting machine and 4 LED bulbs.

We do not even have any commercial construction like shutters / shops nor we have any plans to run a hotel / hostel / mess.

residential construction activity classifies for commercial billing ?
Is this not a Harassments of Linemen ?
or
Do I really need to switch from Domestic to Commercial and then change back to domestic billing again after completion of construction.
