Only for those who are confident enough take note.
Assume a name and persona.
You have received a call from "Amazon to renew your subscription of 79.99 pounds euro"
The agent now asks do you have an Android or iphone.
Well, here's what to do if you have a wifi only tablet or ipad lying around...
Tell them you have [a latest model android smartphone] or iphone 12( when you are using a wifi only ipad)
Don't actually download anything on them
Waste the agents time, yes this is a timesink you are undertaking.
Again not for the faint hearted.
