Even after going through one of the biggest Cyber security compromises in history, Marriott seems to not have taken the time to train their staff. One of their locations in Canada needed to refund some deposit money (I stayed on points and put a deposit down for tertiary costs) and they asked me to email my credit card info to them in order to provide a refund. I obviously said I would not send my credit card detail through email as that is the absolute worst methods to be potentially compromised and they still insisted. I asked their manager to call me and she further insisted. I am just blown away that Marriott, especially with its history, have not have figured this out....end rant...ugggh!
