Songs and playlist all deleted

[Zhancock97]

I had a premium membership but the credit card for my account had expired and so my account went back to the free membership. I updated the credit card for my account then went to Spotify and it still showed that I had the free membership. I logged off then logged back on using the same username and password and it changed back to premium but everything was gone and I've tired recovering my playlists but it keeps saying error and try again later.
