Wait... Bitcoin Cash? You sent BITCOIN and not Bitcoin Cash. Also, AFAIK LocalBitcoins doesn’t accept Bitcoin Cash.
You need to explain better what you did, step by step.
He might be bought a Bitcoin Cash from here localbitcoincash.org?
He should contact the support if he bought bitcoin cash from that site.
It seems that the TXID he provides above is Bitcoin so no bitcoin cash transaction.
@OP can you post your receiving address here?
and share also if where the bitcoin or bitcoin cash comes from?
I hope that you can detail if what you did so that we can help you with your problem.
