First I have to apologize as I know NOTHING about BTC or BCH. If I am posting to wrong forum or this has been asked a million time, sorry. I'm just hoping someone can walk me through a solution to my problem.

I sent BTC to a BCH address accidentally on Oct 11, 2019 to fund an account. The account holder says they can "see" the transaction and are working with their "service?" to fix this. But seeing as how it has been almost a month now and nothing has happened I feel I need to at least pursue on own.

I set up an account at coinbase. I bought bit coin cash (I have a receipt) and then sent the money to what I thought was a bit coin cash address. (I have a receipt) I guess I really sent the money to a bit coin address.  I contacted Coinbase and they said that after the money is sent there is nothing they can do. The account I was trying to fund sent me an attachment showing the funds in a blockchain account? I contacted blockchain and they were very nice but advised me that there are many blockchain sites (I don't really know what they said)  and the gist of it was they couldn't help.

I can provide more info but I do not know what to provide, for security reasons, at this time. If someone has a urge to help and old man recover his money and can walk me through the steps in a childs language I would greatly appreciate it.
