I have an unlimited worldwide subscription valid till 03 November 2012. Skype contacted me via email and asked me to update my credit card which was due to expire. This I did, yet skype still tells me that I have a subscription as shown on my account, but emails me to tell me that that my worldwide subscription is due to end. Late last year when I had a monthly worldwide subscription, they were billing me the monthly amount every week or 2. They are impossible as you cannot talk to a person. It is the perfect way to scam money as there is nobody to access.
