Bajaj Electronics — Havells. Geyser installation

Address:

Flat no:33025, 3rd Block, B Wing,Janapriya Apartments, Attapur, Hyderguda,Rajendra nagar.

Dear Bajaj, electronics,

I purchased Havells Geyser from Bajaj electronics on 31st Aug. Sales person said installation will be done from 24 hrs to 48 hrs.
So I waited for 48 hours then I started calling below Bajaj customer care numbers - [protected], [protected].
Daily I have been calling these numbers at least 10 times, most of the time those lines are either busy or switched off.
Hardly I was able to talk to the person twice, even that time also they said they will call me back with installation status but I haven't received any call.
I am really not sure to whome should I contact for my Geyser installation even after purchasing 4 days how many days will it take for my installation.
Pls help me in this regard ASAP.

Thanks,
Niveditha.
