Fradulent transfers to my account from 'closed', inactive account???

I have had great difficulty getting an inherited property's account moved onto my name, but finally succeeded in early February [new account ********** 649]. The last of the balance on my parent's old account [ ********** 148] was successfully transfered onto my 12_02 bill. It was also supposed to be closed at that time. They are passed, there's only one house, one electricity/water meter, one everything. My account has been properly receiving charges for all services- water, electricity, sewage, rates, refuse, since then. All outstanding amounts on their account settled. Checking today, it's zero, zero, zero every month.

Things have been going ok since then. Today I receive an account with mysterious 'VARESD Transfer' and 'BR transfer' amounting to over 3.5k into my account, making a ridiculously high bill. On investigtion, these so-called transfers were made from the old [my parents] account. A ZERO balance account. So this account- supposedly transferred and shut- is sitting at -3.5 k, and my bill at over 7k!

a] WHY is this account still open? b] How on earth do you justify loading up 3.5k charges on my account, transferred from this supposedly closed account, WHEN THE ACCOUNT WAS SITTING AT ZERO DUE? How can you make a non-operational, supposed to be non-existant account 3.5k credit and rack up that as charges on my account? ITS THE SAME PROPERTY, MY PARENTS ACCOUNT SHOULD BE SHUT.

This smells like *****. What is going on? Your billing department never answers the phone- sat all day trying to get hold of someone, but nothing. What possible reason is there for this? It's whack financing at best.
