I agree with you. I have the same problem. In my account login page it says: "You are going to continue to be credited with 10 GB download traffic per day, until 05.07.2009. It is 140 days remaining.". Although when I am trying to download more than 2.6GB my downloaded file says: "You have exceeded the download limit. Your account is credited with 2.66 Gigabytes per day. 2.66 Gigabytes are equal to 2.660.000.000 Bytes."
That is a fraud. I paid for 10GB per day not 2.6GB. Without having the option to get my money back for the rest 140 days, I have the right to call them thieves..
Get another provider.. I agree
