Seems like you've had a really bad time with your ISP
Hope you get it sorted out (I mean hope they sort themselves out)
It is really annoying when this sort of thing happens, it happened to me as well, I payed a bill on the internet on the first day I recieved it to a company and then they kept sending threatening letters saying they hadn't recieved it and they said you aren't suposed to pay through the internet (why have the facility if you aren't suposed to use it) then they send a letter showing the payment but then they say they never recieved a payment and that they never sent a letter with the payment on it even though it is here and now they want £30 administration charges for making such a mess of things.
At least my ISP is ok at the moment
