Airtel — airtel cheating with 399 offer

Address:

500062

Airtel is cheating with 399 offer for 84 days, when I tried to recharge the offer is not applicable on my phone. When I contacted the customer care they said it will be done in airtel store, when I went to the store they said the offer is applicable only to random numbers, what an unethical practice by the airtel. I am planning to port to Jio.
