You fell for sales guy's trap.
This problem is with every isp you can name, they ask for money first and then send guys for installation and if cable is cut and area doesn't have users then they don't install new cable.
You should email them at
delteam@hathway.net
billingenquiries@hathway.net
Delteam usually replies back within 2 days and do provide your hathway account number, registered phone number and email.
It will be better if you simply state your problem and ask for refund and not write "truley cheeted" or something like that.
Call them on this number too if you live in Delhi.
011 4608 5777
Select existing user option and get to their customer care otherwise they will connect you to some sales team.
Refund process usually takes 15 days and i know it is a lot but it can even take 4-5 days since you paid via cheque and they can simply transfer back.
DON'T GIVE THEM BANK DETAILS UNLESS THEY ASK YOU.
If
delteam@hathway.net calls you then it will be resolved quickly since they have more power than customer care but lodge a complaint to them(CC) too.
Next time don't give isp money first and then wait for them to install the connection, tell them to get their installation team and do it simultaneously or pay via cheque and cancel it if they don't install in 24hrs.
