Airtel — Delay In broadband connection installation

Sir
I have I bought a connection on 11 October 2021 since then I have
received no messages no information about when broadband will be
installed at my home .Your representatives are not receiving calls . I
was told that it will take 48 hrs. for giving the connection since
then your representative came only once and checked the box outside my
house and said that it is not active and it will take 2 days to
activate the box now I am trying to reach them earlier there was
excuse of inactive box now there is excuse of holiday what kind of
service is this, Never expected this from Airtel please provide my
connection ASAP or Return My money.
Please contact if there is any update
