Western Dental Services review: billing

These guys are crooks when it comes to their billing department, I would assess there work as Average at best. Lets get to billing issue. My then girlfriend needed some dental work done in 2007 I agreed to pay for some work, a couple of fillings. All was well. I signed some paper work and paid them Then about six months later she went back with out my knowledge, permission or a new contract with signature for service to be preformed she had several root canals done ( I was told). Imagine my shock when I sent a bill for $3500.00 for service. I immediately called the office and told them they were billing the wrong person, that the girlfriend was in Washington state and I gave them a forwarding address. They kept attempting to bill so I spoke with the Office manager and stated that I had never signed or authorized for any such additional services. They then turned it over to collections. It's still with collections and now they have pushed they original date on my credit report from 2007 to 2011 to extended it. I am taking further steps but these guys are incredibly shady. I have asked for proof of debut and all they send me is the original paperwork of $1800.00 which was completed and paid for. I am following up again on Western Dental but boy what a headache they been. I would stay far away from there Dirty business and billing practices. If I still lived in California I would go down to the courts and file agents them false billing and reporting to the Credit agency. LOOK ELSEWHERE FOR A REPUTABLE DENTIST.
