hit my limit...

[#1]

hit my limit today my last day before next months. I've set the max over usage to 0 when I first connected. But I haven't been cut off. Whats going on? I fell a sleep with the internet TV running and now my usage is 60.11gb but still working fine.
hope I don't get charged extra.

If it's set to £0 you won't be charged a penny m8, the only difference is that your speed will be reduced really low until your next billing month.
Hope this helps

Great, yes that's what I needed to know. Thanks

I reached my limit on Friday, but my service wasn't throttled as I expected it to be. It remained at full speed all day yesterday, but it's throttled now. I also have my maximum extra monthly spend permanently set to £0.00, but I kept checking it yesterday to make sure it was still at zero. Paranoia..........

Always a good idea to check! OCD type behaviour isn't always a bad thing
