Right, its been a mixed case for me. I was on an 8 mbps plan paying 799, that I was convinced to get a VDSL router upgrade for 500 bucks and that with VDSL I will get 16 mbps effective immediate and "shortly" I will get 40 mbps. More than a year passed with no change and I was so irritated that I was on the verge of disconnection. Hathway came in with 100 mbps for 799 and I was all but going to chuck Airtel out. Decided to retain for the landline and that I could switch to 499 plan with 100 gb for 8 mbps as Airtel has been more stable than anyone else and I can see for few days and then decide. Has been the backup connection and some family members are connected to that always.
Recently noticed that speed of all plans for me are now showing as 24 mbps including my current 499 one.
Its been more than 4 years since that promise of 40 mbps of "shortly" getting it.
