I had raised a request for aitel broadband, a representative from airtel followed up and and provided me the details on document required, also assured me the connection will be set up same day if the payment is done before 2:00pm.
Following the instruction, i did the initial advance payment via online, after that there had been no follow up, no response to calls and text messages.
What i am bothered is why a false promise was done if the connection could not have been set up on same day.
Why there is no pro activeness after the advance payment, is it only to get the initial payment false promises are made.
I am seriously doubting on you services and promises. First impression is bad.
4530620 was the id shared for payment.

If it is difficult to keep up with the services you promise, i would request for my deposit back
