How to transfer cash from in my account to Bitcoin

I have had A Coinbase account for several years now I rarely use it and only use it to pay for things. After transferring money in this last time, I found when using Bitcoin to make a payment, it showed insufficient funds, even though the money was in my account! This has never happened to me before! My account shows cash in my account but not in Bitcoin! How do I now move my cash balance to Bitcoin? Thanks for any help on this. Also is there a way to contact coinbase by phone?
