Well, that’s ok then. I was worried I’d get a letter from my ISP. :S
You’re with a rubbish ISP, so what the rest of us get up to doesn’t really matter.
You’ll want to check your original contract. As far as I know, when you sign up for something that’s what you get irrespective of who now owns the company. You’ll either have a limit or ‘fair use’ which, unless defined, means anything they feel like.
For example, I signed up for freedom2surf because they said it was “unlimited and uncapped”. I asked what that meant and was told I would get unmetered bandwidth at the maximum speed the line would provide. I knew the line speed was about to go up so stuck with them. By the time ADSLMax came in, f2s had been sold (to pipex, I think) and I was told that if I wanted 8mbps I would have to change my package - which would be more expensive and have a download cap.
Fortunately I’d asked what ‘unlimited uncapped’ meant by email, so forwarded it to them and told them I wanted my 8mbps NOW. I got a phonecall saying “since you’re a valued and loyal customer we’re going to give you it, on the condition that you don’t go online and tell everyone”. They also said if I went over 100GB in a month I’d get a phone call to talk about malware problems. I went over every month and never got a call.
