ok so a bit more info to help - I am in the uk.  The transaction has been pending for 6 days!  I transferred it to a nano s ledger so when i went on the ledger app to receive the funds it asked me how much I was expecting to receive and gave me a wallet address. I have read that the nano ledger gives you a new wallet address each time.  I also sent  a litecoin on the same day which is fine and in my wallet.  I have contacted coinbase support twice now but due to a backlog they have not responded yet so I thought I would try and solve it myself (you guys, lol).

I have checked blockchain.info using the wallet address and it states 0 bitcoins sent or received from this address

thanks for all your advise, I appreciate it and any future suggestions.
