Airtel — regarding recharge plan rs.399

I have done recharge of data plan of rs.399 having unlimited talk time 1gb/day for 70 days from airtel franchisee shop on my mob no. [protected] on 26/09/2017 but given only per day with one month validity upto 23/09/2017. Whereas i should get validity of 70 days upto 06/12/2017. I contacted shop but he could not sorted out this. Hence, airtel may be directed to increase data validity i. E. Upto 06/12/2017.
