I dont think this is true.. Please dont fall for this scam

as like i did.
In my home i dont get airtel network at all(Whitefield, Bangalore) and based on this kind of posts, I converted all my family numbers(total 5) to Airtel Black connection by including my existing 200 Mbps ftth plan. Not even 1% increase in the network quality, it was shit as like it was in prepaid. Almost 1.5 years in postpaid/black, raised multiple complaints, they dont even care to visit the location and keep closing the complaint saying its resolved.
Finally dismantled black, and converted to Jio postpaid for 4 numbers and one ported to Vi prepaid. In my place Jio is bit better, but Vi also similar to Airtel.
The surprise thing from Vi was, when i complained about network issue, with in 24 hours someone was at my place and measuring all the network signals, both indoor and outdoor. He mentioned about the nearest tower was shutdown and if more subscribers are in this area, they will switch on back! Later after few days they sent me message something like, "we acknowledge the problem, but unfortunately at this moment we were not able to resolve it, but we will keep improving our service". This was not surprise or unexpected from Vi when giant like Airtel itself does not bother to resolve the complaints, how on the earth we can expect the resolution from Vi is almost verge of collapsing.
