If you are a MasterCard customer, like me, and have any concerns you’d like to bring up with the company they have a very convenient PDF with toll-free numbers for all countries available here:
https://www.mastercard.com/_assets/docs/GlobalServiceTollfreeNumbers.pdf
I was very lucky to be able to find the link, because their customer support number wasn’t advertised anywhere on their website for my country!
What I did was mass edit all my comments. According to reddit customer support (about a year ago at the time), they do not retain old versions of edited comments.
