Hi,

I have sent a bitcoin amount to a company, the transaction has been confirmed 2 days ago but the company deny it, they said the transaction failed, is there by chance anyway to prove that the money on has been sent ?

Thank you for your help

PS: My transaction was not confirmed for 5 days and i used viatbc accelerator to make it faster, could it be linked ?
