Water load of rubbish!!

So on the day we completed, I duly spoke to Southern Water to ask them to put the account into our name but telling them we hadn't moved in and needed to keep our existing account in Chilbolton open. No problem they said, keep the bill where you are, no bill due for the new place, tell us when you start renovations. If only... They then sent us a bill for it. I called them. They had apparently processed us as moved in, in spite of knowing we hadn't. They promised to put this right but didn't ever send us anything to suggest they had done so. Then this week, they sent us a dd cancellation/final bill for our current house. doh!! I've just called them to ask why they did this and had to spend another half hour on hold until they admit they've got it wrong but say - 'oh, we can't reinstate the payment because Alan set it up'... Exit Liz through the roof demanding to speak to someone more senior... at which point I somehow get cut off... Finally re-establishing contact and after another 10 minutes on the phone they do admit that as they cancelled it, they can reinstate the payment and they promise to sort it all out and give us £20 as a gesture of goodwill. I icily said thankyou and now wait to see whether they manage to get it right this time. Don't think the local bookies will give me evens though...
