Airtel — airtel 399 plan of 4g internet and free calling expired in 1 month

Address:

Jaipur, Rajasthan, 302017

I bought the new 4g sim of airtel for my 4g phone and recharged sim on 4 july 2017 for the rs 399 plan i. E. 1gb 4g internet data and unlimited calling for 84 days as told by the company. But the plan expired in 1 month 7 days. The company is cheating the customers on the saying that the plan is for 84 days, but the plan is expiring in 1 month only. This is completely fraud plan by airtel, cheating the customers - showing more and giving very less. My airtel no is [protected] and mail is
