@Juan-Diego1 Read the link posted by @Colleen253 carefully; personal life circumstances and medical issues of any degree are no longer considered "extenuating."
However, if you covered your trips with personal travel insurance (which I truly hope you did), your policy may compensate you for some portion of the losses. Hosts generally believe that they should not be treated as guests' de facto insurer, so if you request an exemption to the cancellation policy that you agreed to, I recommend humbly acknowledging that it's a special favor you're asking for rather than something you're entitled to.
I don't see any good reason to contact customer service. This is purely a matter of the agreement between you and your hosts, not a technical or service issue.
