We sign up for pre authorized payments with hydro and they have taken out OCT bill 3 times now. We paid it on Oct 20th and so far taken money 2 more times after that. Then say we won't be able to give you your money back for a month or so. Like what???? Just send the money back to the account you took it from. Left us with nsf fees the first time, now they straight took another 174 for no reason from the account. Like wooow and now we wanna get this pre authorized payments off the bank account and they want 300$ from us before we can do that.
