I spoke to a CC exec a couple of hours back.
She said that the upgrade is underway and will be done soon.
When I asked her about the FUP on my current plan, she said that there's no mention of any FUP on the plan I'm using so there will be no FUP after my bandwidth is upgraded.
This isnt Airtel's generosity but a proof of how incompetent their CC have become these days.
Just called up Airtel CC. Spoke with the Sr. Supervisor at CC. The lady informed me that the speed upgrades would be completed by end of June, which we all have discussed in this forum several times now. She told me that on my current plan, Rs. 1699 (with 1 MBPS speed), there was a FUP limit of 100 GB, which would not change even on speed up-gradation. After the speed increase, once I cross 100 GB, the speed would come back to 1 MBPS and not go to 256 kbps. The speeds / tariffs /plans given on their website under tariff section are applicable only to new customers or those who get their plans changed to new ones. Existing customers would continue to enjoy the same FUP limits & their speeds would be reduced to half (or what they currently have). I really hope that this is true. Will get to know for sure once the speeds are upgraded. Till then.... have my fingers crossed !!!
