Airtel — no network at home since 26th april 2019. mobile no [protected] & [protected]

Hi myself kiran bhagwan tamhane. My airtel no is [protected]. This no. I recently ported on airtel i. E on 25th apr 2019. But from 26th apr 2019 12:00 pm network range gone at my home, address is mentioned above. I raised complaint[protected] on airtel & they committed that they will solve the by 30th apr 2019.
I replied airtel on call to put note that if issue will not solve on 30th apr then i am not going to pay this month bill.
On 30th apr 2019 i called airtel again around 10 pm and they told me that they will escalate this issue. Till now no one contacted me and no one visited to my location for survey also regarding issue. Today again i called up airtel again they told me that they will escalate to network but no response from airtel.
After porting to airtel immediate from next day i am not able to call anyone and not able to received call from anybody. Airtel is taking this lightly as in my home having total 3 airtel connection and every one facing same issue.
Now a days facing lots of problem with telecom operator like airtel & vodafone and company not bother about it. We are not able to use service most of the time then why should we pay for that. This is happening every 2 month, so why every time customer should face such issue. There should be penalty on telecom company like airtel or vodafone if customer not able call or not able to received call, data connectivity issue. There should be new policy to implement from govt. That if anybody face such issue & company will not resolve your issue withing 4 days then you dont have to pay bill for this month.
Request here is to take strict action against this otherwise they will not improve their network connectivity.
