The word 'pethetic' is a real understatement

My account was moved over from Nashua mobile to Altech Autopage. Altech Autopage didn't debit my account for December. When I called in January I was told that with the transition my account details didn't pull through on their systems. I made the necessary arrangements with Marcia in the accounts department to manually pay Decembers premium in. A week after making the payment they went in my account and double deducted the amount which by then wasn't even the corre4ct outstanding amount...\I wonder however they got hold of my banking details to do this???'. I called in on the 2nd Feb 2015 and spoke to a legal supervisor who pretended to be the accounts supervisor who gave me the companies turn around times to resolve the matter guess what. 2 weeks later and nothing has been addressed at all. I called in today only to be transferred from pillar to post for 25mins. When I eventually got a hold of Collin he told me that he was in the legal department and that he needed to find out what the problem was. A promise of a call back is due by 14:15pm today
