when you have problems with a web wallet, contact their support. I don't think anyone here can help you with this.
someone got the same problem last year. here's the thread for that.
im already nervous waiting for my wallet to sync but its not only 1 address its all translactionssomeone got the same problem last year. here's the thread for that.
pretty nervous,sended a message to blockchain and still no answer
if you don't want to wait you can export your private key to a different wallet. you can get your priv key from Import/Export -> Export Unencrypted. if you cannot access that page then you're out of luck.
you just copy the private key of an address that contains your btc. then import them to some other wallet.
for fast use I recommend electrum if you don't mind sweeping instead of importing (the btc in your address will be sent to another fresh address.).
you can also make another blockchain.info wallet and import the priv key to that wallet. my [old and abandoned] blockchain.info wallet works fine just now.
there's also multibit but I don't use it so I don't know much.d.
