Just started booking a flight to go home for a funeral and when I went to my account, 50,000 SkyMiles were missing and used in the market place (practically draining my SkyMiles).

I've already pursued and completed the initial steps (i.e. Obviously reporting it, cancelled my Amex, changed all username password info associated to this, etc.) but I had to leave a message for the srevenue fraud dept (? Or whatever it was called..) and now my mind is racing: what if I can't recover those points? What if whatever investigation process they have is limited/not extensive, also resulting in my loss and a "welp. You were smart to react by canceling your card and changing your login info for everything. Sorry this happened to you. Better start flying again soon to start gaining those point back."

At at the end of the day, I'm out whatever money I'm going to have to pay out of pocket to attend the funueral which sucks but of course will have to be done, but has anyone ever had a similar situation to this? What was the process like and did you recover your points?

The worst part: when I immediately re-checked my app, there was some bogus email address in place of my own. I'm incredibly uncomfortable with this and feel vulnerable. How could this have happened? I'm intensely careful with all personal/financial information and have worked extremely hard for 10+ years to establish the credit/rewards that I have.

Any insight on the following would be immensely appreciated:
1.) will my SkyMiles points be returned?

2.) How could this breach of security have happened so I know how to avoid it?

Thank you.
