Airtel — i am not getting the " same recharge plans" as everyone does

Address:

600 106

Sir,
I am a premium user of airtel prepaid sim (Ph. No :[protected]). Many airtel users known to me in my family and friends circle, everyone of them are able to avail the 399 offer (Rs 399, 70 gb for 70 days).
Even when this plan came before for 84 gb i couldn't avail it and when i contacted the customer care, they told this offer is available to only select users, but why not me?? I am also paying a hefty amount for my sim and also availing the rate cutter plans, but it's becoming non economical for me and it's a spendthrift.
Other sim carriers are offering well cheap plans for the cost and is available for everyone.
Please make sure i am getting this offer or else i would like to have a conversation with the senior officials or else there is no other way than porting my number.
