In case that this wasn't agreed before the loan was issued, then the borrowers do not have to pay back any amount of BCH. The only thing that they do have to pay back is lent BTC + interest as agreed upon the initial terms. If the accused is indeed demanding that BCC be sent to them as well in the fashion of "send BCC or else X", then then a negative rating is warranted. I do have to take a better at the timeline of the changing statements.
It is optional for you to pay the BCH.
