Earlier they had a plan for 1999 with 80 gbps etc..
That was from 2013 if I recall

Then they had new plans where the rate was dropped to 1300 for the same package, but they conveniently "forgot" to inform me. Neither did they automatically change it.

On contacting they changed it and said its the "customer's responsibility to be updated about the new plans". Isn't this a scam? Am I entitled to take them to court? or to get compensation?
