I earned three Skype vouchers. I received the codes and for the last 32 hours I have been trying to redeem them but I always get a message stating "unknown error occurred. please try again later."
How can I redeem the codes which I legitimately earned from using Bing? It's been more than one day since I received and last tried using them.
I have the same problem...I emailed Skype Support and they told me to try a different browser, clear the cache and empty the cookies but to no avail. I even tried a different computer at my friend's house but still got the same error message "An unknown error occurred, please try again later"....very frustrated!!
I just tried the same techniques you mentioned. We have to mention this issue to Bing.com and complain on their boards as well. It's such a shame that a company like this can be trusted so much yet it takes advantage of customers with false advertisement.
