Is there anyone who can help me decipher my statements?

2/10 we got our account emailed to us, it covered the dates from the 2/10 to 2/11, taking everything into consideration, we were $35 in credit. Today we get a statement emailed to us, it covers the dates from 2/10 to 2/11, taking everything into consideration we are now $85 in debit. I ring the owner who bites my head off when I explained that I was worried she has charged us for the same period twice. I explained the two statements etc, but she didnt care. Im sure she is wrong, this statement should have been for 2/11 to 2/12, well thats my understanding.

Anyhow, now Im stressed, I dont understand my statement. Can anyone help me work it out please? And its not relevent but i was meant to pay today but forgot to take the money with me this afternoon.

please any help would be greatly appreciated
