I bought a Minternational pass to use this past Monday. When I tried to activate it it got stuck on "Activating". I had to wait most of the day to talk to customer service. Once someone was finally available, after trying several things they told me there was a "backend error" and they would have to escalate it to another team to fix it "in 1 to 4 days". I was on a 4 day trip so that seemed pointless, and I asked for a refund. You can see in the chat that they agreed. I bought a SIM at a local store and finished my trip. When I got home I saw that I didn't get refunded and that the pass was now active. I went back to customer service and asked for the refund. After going around several times they kept telling me that their "policy" prevents them from giving me the promised refund. They eventually advised me to do a charge back with my credit card. Ultimately I did that and my card company gave me the money back, but because it was a small amount (~$25) the card company just ate it and didn't take the money back from mint. It was an infuriating, stupid, waste of time all around, on my trip and after. I would never buy a Minternational pass again, and it really has me thinking of leaving mint when my prepaid contact is up.
