I am a worthy customer of airtel for 10 continuous years . I have been using these airtel broadband, landline, mobile connection( postpaid), DTH all possible airtel products for 10 years.
Airtel provides best customer service and it is completely reliable. I would also agree to some people who claim that it’s costly and they would get better services by any other ISP at same price. But common! airtel provides quality so it will also charge for its 24 x7 service.
In 12 hours my problems are solved regarding any defect.
