BSNL can do a lot of things to ensure customers are satisfied but the sad fact is they don't. I had to replace my twisted pair cable from the DP point on the ground floor to my home at my expense. It is no point trying to get these morons to help. My neighbour, a sr. citizen and a widow in her mid 70s had issues with her landline the BSNL. She complained and the linesman came over but demanded Rs 300 to fix it!! These people are pathetic!
If you take an Airtel vfibre/copper, even if as a backup, it may be a little slow in comparison but at least you won't be pulling your hair out in frustration every time the
GPON drops a link due to a faulty cable. Also, if the connection is via a LCO you could approach them too.
Airtel is moving away from copper and replacing it with fibre and it's only a matter of time before they wire up your building. I had to wait for years for
xstream fibre to be introduced in my residential area. Airtel is slow, v slow in rolling out infra. But now we have a choice of 3 tier 1 providers in Eastern Pune (Airtel,
Tata Sky, and You BB/Vodafone) along with a clutch of tier 2 and 3 operators.
