My phone is killing me...Part 2

Tonight I made a phone call to Vodaphone. There's something not right with how much my bills are.
Since upgrading my phone, my phone bill has increased month on month.
In June it was £41.79.
July hit £49.40.
August was bad at £53.32.
My latest bill is a whopping £59.29.

Now I've looked at my bill properly, the kind man at Vodaphone confirmed something is wrong.
For me to be incurring these charges, I need to be making 10 hours of phone calls a month and sending over 300 texts. That's 10 texts a day.
I don't think so.

So tomorrow I phone Vodaphone again and talk to someone who can give me refunds. I reckon at least £50 is coming my way in over-charging, which is nice.
