Thanks for replying everyone.

Some background. None of the networks keep detailed records of where you browsed or what you connected to. They could spend hours doing a low-level investigation. But of course, its much quicker for you to check your handset.
So, go through your handset in detail, take your time to do it properly. Check what is syncing and updating.
Check your data counter and consider installing one which provides a historical log.
Once you've got actual proof (either way), then you can make a complaint to Three. Follow the proper procedure, put your complaint in writing. Make the complaint concise and accurate, don't go off on a tangent. Enclose screenshots or printouts of your proof. Tell them that you request a full investigation, a full refund of the charges and an apology.
Now allow them time to investigate, when they do respond think about it before responding.
Should you reach a deadlock with them then you can go to the ombudsman service.”
Unfortunately I don't already have a data counter that can tell me what used data and when, but once I get connected again it'll be the first thing I do.
Without that though, how am I meant to get proof? There's no way for sure I can find out what was using my data, I can only guess.

Thanks, I may well try that. Though the one plan could end up costing me more, not sure they'd be willing to switch me to it without extra monthly charges.

My Nokia Symbian has similarly connected on it's own, despite all the settings been that it asks first. Deleting the email client cures it.
As the OP has an internet app permanently connected and syncing, it seems most likely that it's responsible?.”
It's only the Google Mail app that comes with Android, it's designed to be left on all the time and I've had it constantly syncing while the phone is on for over a year now without any trouble, even when I only had 500MB data allowance, so I really doubt it can be that.

I've never tethered my phone and I don't think that functionality comes with the phone, I've never downloaded an app for it either, so it can't be that.

Not challenging the charges would be a huge error unless you knew exactly what caused it....
Question for the OP...if overnight at home, would your Wi-Fi be switched on?”
My Wi-Fi wasn't on no, perhaps in future I should turn it on while I'm at home, but I generally don't bother unless I have bad signal.

Sounds like a mistake at their end to me. Even the most data heavy app is going to really struggle to use 2.5Gb. You could watch a couple of films and not go near that.”
I did ask them on the phone if they could find out how much data was transferred that night, they weren't able to tell me though. So it seems a detailed explanation of when data transfers took place isn't available. But if it was taking place as I got the texts then I wasn't actually doing anything with the phone at the time anyway.

After uninstalling this game, the battery problem stopped. Clearly this game was still doing something when it wasn't in use. Can Three see any other instances when a high amount of data went from your phone over their network when you were unlikely to be using it (I'd imagine that although they can't see what the actual data was that was being transferred, they can see when and how much data has been transferred)? Is Three's data counter in real time or is there any delay? In this case, there could possibly be some liability on their side, unless they make you aware of the delay. Also, when the data appears to have stopped building up, can you recall doing anything with your phone at the time?”
No new apps have been installed on the phone recently no.
I didn't ask about whether there were any other times there has been high usage at times I'm unlikely to use it, but then they did tell me that the most I had ever used in a month before was 600MB, and this was 3GB in half a month, so this month is very different to previous ones.
As I replied to the previous quote, they said they weren't able to give me any details on when and how much data was transferred.
I don't know if their data counter is in real time or delayed. I wasn't doing anything at the time as I was asleep all the way through the data usage (going by when all the texts were sent).
