Be aware of dentists

In november 2016 ive done my root canal by these dentists they done a good job no doubt about that however one year later i get a bill when questioned they said the medical aid did not pay i sent the medical aid the details and was told that this will be sorted. A year later again i was told that i need to pay and spoke to medical aid they said that this was paid i left it now i was handed over due to non payment. I feel i was ****ed by the dentist and the atorneys now iam trying to pay the people and they are billing me more then i should have paid
