I think this could be a way for you to change the dates of the KLM one without a price change. I'd at least try that one first, since you're likely to be in for a fight about actually getting cash back anyway!
The whole Covid19 situation has no impact on KLM's free cancelation within 24hours policy. KLM not giving cash only applies for regular cancelations, not for the 24hour cancelation service they've been offering for years. You can expect the refund to take 2 to 8 weeks because of the current circumstances.
