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.
Be aware about Ledger Nano S, it uses legacy and segwit type of addresses parallel on the same device, so you can easily miss the proper wallet. Does your wallet address starts with 3 or 1? 3 is for Segwit type of address and 1 is the 'old' the legacy one. When you log into your Ledger Nano S at the first time you are prompted if you want to use bitcoin or bch, after if you choose bitcoin you are prompted again to select legacy or segwit address. They're totally different. If you have choosen e.g. segwit first, and you used that address to receive bitcoin and after you switched to litecoin and back again to bitcoin, maybe you missed the address type. There's a switch in the Ledger Chrome bitcoin app where you can change the blockchain (looks like a chain I have checked blockchain.info using the wallet address and it states 0 bitcoins sent or received from this address

) you can try that too to switch between legacy and segwit.
