Western Dental Incompetence, fraud, harassment Orange California

The Over a four month period two root canals were done on my daughter plus other work totaling $2700.00 that was paid for in advance using care Credit. Special deep cleanings that were also paid for were never performed. Both root canals failed and we had to get a second opinion because they didn't seem to know what they were doing while over this four months my daughter was in pain. At the second opinion we were informed that the tooth needed to be pulled and the root canals merely prolonging the inevitable. After notifying Western Dental in Whittier, Ca. we were going somewhere else and showed proof that the tooth had to come out and deep cleanings which Western Dental said they performed and charged for were never done and still needed to be done. Throughout this ordeal I had documented everything that happened and also filed two complaints about incompetence with Corporate which were not responded to. After sitting down with the office manager we agreed to a refund of most of the charges made to Jennifer's Care Credit account. After two weeks we saw a Credit of only $163 of the $2400 actually was made. The office manager didn't understand why and said Corporate was still reviewing the case. I finally got tired of dealing with Western Dental and went and filed a dispute with Care Credit. On 4/7/17 we finally received a refund of the full $2700 on her Care Credit account. On Tuesday 4/11/17 I received a call from Western Dental collections telling me that now that they refunded the amount to Care Credit we now owed Western Dental $2500.00 and that I needed to go to the office and pay that amount???!!! The refund just took place. We haven't even been notified in writing what was taking place much less requesting payment. I called the office manager who also didn't understand and would get back to me. How could a company like this be allowed to do business!!!??*****
