The person who owns the BCH address also owns the BTC equivalent. They are
the same and you can import private keys from BTC to BCH and vice versa. So, all the seller has to do is import their BCH private key into a BTC wallet and send you the funds back.
Can anyone confirm these funds will never go to a newly created wallet/Receive address for me please?
The funds are already there as the transaction has confirmed.
Will the BTC funds be in the BCC/BCH wallet receive address of the company I sent them to, just not visible because of wrong currency?
Any help much appreciated, Reward will be paid too for help leading to the return of my hard earned funds. It's about £10,500 GBP at time of sending so talking at least a £1000 for it's safe return, if you want more make me an offer to consider.
The only one who can return the funds is the owner of the private key to 12PYBy89CUJkoJyar48E2Shys7GBMY4CxJ , which is your seller. There is no way for someone to earn that recovery reward other than explaining and suggesting next course of action.
