Incorrect Billing

My account was migrated over to Autopage from Nashua. During the time i was transfered, my contracts expired and i requested 2 x upgrades for my existing 2 contracts. In January i had to phone in to request a statement as i did not receive any statements from Autopage. My account is in a mess ever since the first debit went of. If they dont double the debit orders then they over charge me. i need some urgent intervention as i just get no service from Autopage.
