After doing all my research it looks like it's only the Chase Sapphire Reserve and the Amex Platinum that still offer this .
Correct me if I am wrong?
There are other cards that have return protection as well: Delta Reserve, Hilton Aspire, Marriott Brilliant, Blue Cash Preferred, and Everyday Preferred (the latter 2 with only $95 annual fees as opposed to the others with $450-$550 annual fees). Plat Business and Delta Reserve Business both have it as well.
Not familiar with process on CSR so can't comment.
