I got a message from so called "FIdo" to send information about my account because there was a so called problem. And yes, I stupidly send this information they asked. About a week later I got a big bill of 1342$. And it's usally like 30$ a month.
I called like 2,3 times at fido and they always says that they'll call my back byt they never did. So what should I do ? I'm not paying this for sure.
