Airtel — about very slow 4g internet speed

Address:

400015

I am using prepaid number [protected].
I hve active 4g net pack of 1.4 gb per day.
In my house I am not able to get even
10 kbps. I am trying to contact customer care from last one and half year they saying either server is down or network is upgrading. How much time it takes to up the server or upgrade ? I am sick of this. I have tried open network it show position of your towers but not showing where to launch qwery or complaint what the mess is this. I have paid for the 4g internet service and you are fooling us that wait wait it be better soon.
Please please sort this out as soon as possible.
