Airtel — new broadband connection not installed

Address:

Chennai, Tamil Nadu, 600052

This is regarding my new connection request, caf 4510814. Job id[protected]. I was promised the connection would be setup by monday eod, there was no call or any communication.
Tuesday one of your field tech supervisor by name prem (+[protected] calls me and says the connection will set it up before 9pm and shares the contact for the installation person kadhar (+[protected], who gives his work to another installation person by name kavi (+[protected] who tells me the connection would setup before 9pm.
Around 8:50 pm another tech calls by name veerapandi selva (+[protected] calls me and says we will do it by wednesday 9am on priority.
I am trying to call all the people involved and non seems to take my calls nor respond. If airtel cannot keep up to its commitments why do you even advertise your services. Now tell me, will i be getting the connection installed today or should i take look for local cable internet operators for my needs.
