After a month of bad service and about another month of fighting with PlusNet about my MAC code (including a failed attempt by PN to make me pay my entire annual subscription in spite leaving within the 45-day guarantee), I've finally received it and, thankfully, migrated elsewhere. Now I'm getting what seems to be a slightly faster connection with fewer disconnections.. for half the price of my old PlusNet service! Hooray for e7even.
If you're tired of getting jerked around by PlusNet, fight back with your wallet and go elsewhere. If nothing else, it's just a really satisfying feeling when that new DSL service kicks in and you realise PlusNet is out of your life for good.
