Help Freedom Mobile Fraud

(I apologize in advance if this is the wrong subreddit to ask, but I genuinely don’t know where else to go besides r/ freedommobile)

So 3-4 months ago my entire family switched from Rogers to Freedom. We all got international plans with 10 gigs. It was an infinitely better deal than Rogers and we were all very happy.

A week ago one of my family members was billed an INSANE amount. When we checked the bill it said we had been making calls to the most absurd places like Botswana and Burkina Faso. We never have any reason to make calls to these countries, and there were 50+ of them in only one month. We assumed it was fraud and called freedom. They helped change the number and said they would reimburse us the $200.

Flash forward to now: we have been billed $700+. TWO of my family members are now supposedly making calls to these random countries (including the one that we just got the number replaced). Not only that, but Freedom is now charging us an additional $200 (the 200 that they said they would REIMBURSE).

Has anyone had this experience?? What in the world are we supposed to do?? Any advice would help, and if anyone from Freedom has any input it is very welcome. Thank you.
