Thank you to all who replied,the issue has not yet been resolved even though I have attempted all your suggestions,I have requested that the vendor send me a screenshot of their wallet as proof that the funds didn't arrive,I don't know if that's a good idea or even if the vendor will be willing to do so,but I'm running out of ideas,grasping at straws now

I will try that Sir,thank you so much for your help.

Much appreciated dude,I will contact the vendor again,however they have told me that they are sure their wallet is sync'ed and up to date,they even said they had taken a BTC transfer/deposit since I sent mine,but blockchain.info does not support that
 

Hi dude,
I really appreciate the reply,the wallet address I sent to is "1857fhkHStyLyrAgTuCMHvxkyuxoXegnvJ",which I copied and pasted when the vendor sent it to me so I'm pretty sure that is their wallet

Hi all,
I,m totally new here and am looking for a little help from some more experienced Bitcoin/Blockchain users than myself,
Last night,I sent funds from my Blockchain wallet to a wallet address I was given by the vendor,after 3 confirmations on the blockchain I assumed the vendor would receive their funds but they did not.
Now,hours later,with multiple confirmations on the blockchain,the vendor still says no funds have arrived in their wallet,I'm totally confused here,I have sent Bitcoins to many different wallets in the past and have never run into this problem.I hope if I post the txid here,a person with the knowledge to look it up and check it out could shed some light on the issue for me,so here goes;

txid:bed5d7b809254fe066d1f913c3a409ff2107517d647e9a2f3ff1cc974b0cd445

Its now got 68 confirmations but the receiver still says no funds have arrived.

Please help
