Okay, so according to slingshot's website we qualify for $10 off our homeline, I put our address in and it has the price as $42
I checked our vis bill and we're still being charged $51!
It's my dad's account so i think it's be a waste of time if i tried calling since dad would have to authorise it and he's not here.
So if someone from slingshot would like to help me save my dad money for a change, that'd be much appreciated!
