It doesn’t matter how the data is being used unless there is a limit on p2p data. If they can’t show you that, they are in the wrong and improperly segregating your p2p data.
Again, unless the contract allows for special treatment of p2p data, it’s as simple as they are not providing the service you contracted for.
So, you start with;
You are charging my p2p data use against my hotspot allotment. I don’t find where you are able to do that in the terms of the contract I’ve signed with you. If you can’t find a clause that gives you the right to do that, you need to stop doing that.
If you won’t perform as the contract we entered into directs, I need you to cancel the contract and refund the balance of this months fees that I’ve already paid.
So, which is it going to be?
