Airtel — my pack

Address:

Indore, Madhya Pradesh, 452005

I shubham sharma using airtel network.
On 13/09/2017 i had applied for port. After that i received a call from airtel and had a talk with nisha pawar she asked whats the problem? Why you want to port.. I told her 2 complaint
(1) idea is offering good combo packs of net and call that was on recharge of 399₹ 1gb/day and unlimited free call on all network for 84 days
(2) not getting proper 4g network in my house

Then she told me we cant offer you same pack but we can offer you on recharge of 399₹ 1gb/day and unlimited call on all network for 70 days
Cause plan has been change and validity of offer is reduced from 84 days to 70 days
I said i'm ok with this offer. Then she said but you have to recharge with 399₹ within 24 hours and then i made recharge in few minutes with mean of airtel app.

Second problem was 4g network issue in house she noted my full address and told we will be checking it.

According to recharge i should have got validity of 70 days but my validity is over and today (11/10/2017) i have to pay for net call and everything according to 70 days validity should be upto 22/11/2017

I call airtel customer care today (11/10/2017) on 11:27 a. M and had a talk with senior executives sandeep malviya. He told me that there only one cause of portablitiy is mentioned over here that was network issue at my place and no offer is mentioned. I told him this is not my problem that she has not mentioned offer i'm fool that i will recharge for 399₹ when i'm getting same offer for 349₹ she must have offered me thats why i had recharge for 399₹. Behaviour of sandeep malviya was also not good
I'm unhappy with airtel
I have paid for net and call i should get it this is my right
