I purchased the "Unlimited World" program from Skype, that offer conferencing service, for one year on April 27, 2008. They also have “Fair Usage Policy”; subject to a fair usage limit of 10, 000 minutes per user per month. Once this limit is exceeded Skype will charge normal SkypeOut rates and a connection fee for any additional minutes used. In July 2008, they suspended my program and at the same time they charged me for all calling. I had be charged extra $50.00 in July, extra $80.00 in August and extra $25.00 in September. I could use ONLY for few days in October 2008 and January 2009. When I complaint about it. There is no way to reach them but email only. It usually take a week for getting respond. Their answer stated that if they found that calls make from account more than 6 hours in a day. They will suspend the account. But they didn't refund the money.
