Just a post to say how quick a problem had been resolved. I got a mail yesterday saying I'd exceeded the monthly cap and was now on 128k. A quick look at the logs showed a problem had automatically changed my package to a lower allowance. I raised a ticket before going to bed and got a sms first thing this morning notifying me it was sorted. Having been elsewhere in the broadband market - this is probably the best turnaround on a support issue I've experienced.
