Yesterday I clicked on the Ask Jack app in the support area and asked the agent to BLOCK - ALL THIRD PARTY APPS on all of my phone lines.
It took about 5 minutes to get this done, and now I will not get any surpise charges like BANGO on my bill.
Hopefully this will help those of you who have not been hit by this scam yet.
NOTE: Keep in mind that if you do this, you will not be able to make purchases that use your phone's Fido account to make the payment. ( I think things like in-game purchases are what would not work ).
Hope this helps many of you.
