Made a reservation on the Marriott website for a Protea Hotel in Cape Town containing a free cancellation clause on the day of arrival.
However, I got an email today from Protea saying they did not receive any payment and will cancel my reservation in 24 hours.

Seems like there is a major miscommunication between Marriott and Protea.
I already send an email reply back to Protea but it responded with "out of office". Now what.
