It is highly unlikely that the card issuer would bother to go to the time and expense of responding. Once that is the case, every second expended is a further waste of time and money. Thus, many chargeback disputes are simply resolved in the customer's favor by default.

Although it is hard to imagine that this matter would be reopened short of an investigation showing that OP is part of an organized gang which drains these cards, there is also nothing OP can do. He has disputed the charge, he has received a credit and that is the end of it. If something arises in the future, he can deal with that.

The advice to simply document everything is sound. Turn it all into a PDF file and archive it wherever you archive other such matters.
