I had literally the same issue with the plan change, usually Airtel plans take "2 hours" as per the 121 team, but in reality within 20-30 mins the plan is changed over without much issue, billing is pro-rata and pretty fair to users / airtel as well.
When I had requested a change to the new plan, they told me the same 2 hours, 1 odd thing I noticed this time is I did not get any SMS for the change -- usually you get an SMS when the change is approved/added in etc.
Anyways, it was late in the day (10 PM? or 11 PM) so I tried the next day and no change in plan.
So I called again and was told that I have to change the
router to support 200 Mbps and have to pay 900 for this, now I'm using a non-airtel provided router and told them I will continue to use that and just change the plan as the
Huawei ONT supports upto 1000 Mbps/1Gbps. The person passed on my call to their supervisor, confirmed the Huawei model etc and said OK everything will be done by tomorrow 11 AM
Repeat the above paragraph x 3-4 times across the next 3-4-5 days, got the same assurances, same "We have noted it on the ticket, it will be done, it is approved etc, It is assigned to a different team etc"
Then I gave up and wrote an email to
[email protected] with everything in it, my Huawei model# and got a call the next day and the plan finally got changed over.
Not sure why Airtel does this always really with their routers/modems and cause confusion,
When vFiber (VDSL) connections were being setup, the first batch of users got a nice Huawei modem which was far more stable than the Binatone ones, the Binatone one needed a reboot so often to stay in working.. maybe I got a bad piece.. every time I complained I got a message saying they'll replace it but Huawei is not available.
When FTTH connections were being setup, a few(?) users got a better Huawei ONT which had WiFi etc inbuilt, later on they provided a non-wifi huawei model, They even provided a
D-Link Router which connects to the Huawei ONT which already supports both 2 Ghz and 5 Ghz bands, not sure why they are so keen on changing these so often
