Ridiculous ergon bill

Hey guys,

Just wondering if anyone's in the same boat. Just recieved my ergon bill for Jan-Apr and the cost is $1,800!!! It's usually sitting around 700. We do have a pool, however my partner works away so 1800 for 1.5 people for 3 months seems ridiculous.

Anyone else had a similar issue, and any luck trying to get Ergon to knock it down? Want to see if it's even worth putting my big girl pants on and phoning them....
