False Advertising

I app**** for a credit card as they advertise that you can use your credit card locally and internationally wherever there is a master card logo. I was advised today that I can’t pay an online provider in Mauritius and that I will not be able to use my credit card at any ATM in Mauritius. The whole reason I got the card was as a back up plan for my upcoming holiday. I have a screenshot of where they advertise that the card can be used both locally and internationally. This is deliberate false advertising. If it doesn’t work overseas then they should replace it with a Standard Bank card as they administer the RCS credit card
