Data usage

I have had an uncapped 4meg line for over a year. I was throttled due to excessive usage last month so upgraded to a 6meg line on the understanding that I would have 150gigs per month before being throttled. This is EXACTLY how its been sold to me. It's now the 3rd of the month and I've been throttled for excessive usage.<br> <br> I phoned this morning and your call centre told me it was because it was based on a rolling calendar month. This is not how it was sold. They then put the phone down on me. I phoned again and was then told that the other person was wrong and that I only get 5gigs a day.<br> <br> So tell me, if your call centre people contradict each other, it clearly shows they don't know what's going on! I was sold 150gigs a month. If I want to use that in 10 days, its my problem! And every month my usage gets set to zero on the 1st.<br> <br> This is how it was sold to me. Either fix it or cancel my contract with you and I will take my business elsewhere.
