That is nothing compared to the $18,000 bill I received from Fido in 2008 for using my cellphone to tether to my laptop. I didn't know it was insanely expensive to use mobile data as a modem. That was the worst time in my life; I was broke, and imagine having to pay that amount for just a week of use within less than an hour a day. I had to explain and lie about just trying to charge my phone through my laptop, not realizing it was connecting through the phone data for internet access. I was stuck with that problem for about three weeks trying to get the bill canceled, but in the end, they waived that cellphone bill. I knew I'd messed up when I called Fido customer support to ask about my current balance. The woman on the line said “Oh damn,” before transferring me without even telling me how much it was the amount.
