In the past, I have used/abused Airtel not counting upload in the FUP, uploading 100 or so TiB over the course of a few months. I had to get my airtel connection disconnected due to them not supporting my area but now I am back to using their services. As before, I tried to upload a few terabytes and woke up a few days after my connection with my speed limited to 1Mb/s upload and download. I talked to both an engineer and the backend team and they both confirmed that I had used up all the data in the FUP and had to wait for the data to reset next month. The only option provided to me was to buy more data to continue using their services
