Re: I love messing with Telstra!
Overpay, if you underpay, they may just charge you fees for not paying them enough, send them 1c per day for the next 20 days, that will make accounting fun for them :0)
Phone them and tell them you need to make a payment plan up, as you just can't afford such an outlay in one go, dont tell them the bill number or the amount till you have them all wound up, then tell them the bill number.
I did put something here, but it vanshied, I think
