I did not get to use almost $9 of my $10 credit I purchased.
I waited until the day before the credit would expire and tried to use it, but their software would not allow me to call. I contacted their support and they did not respond until the next day.
They said my credit had expired and I was out of luck. I said I contacted them the day earlier, but they did not care. They just kept my money. The software continued to show I had a $9 credit to use for a month, but would not let me use it.
I even posted on GetSatisfaction, but they ignored my requests.
I will never buy credit from Skype again!
I recommend that all people not buy credit from skype as you may not get to use credit as you expect.
