In 2007 July I went to the dentist for fillings, I was using my medical aid and was of the idea that all of the expenses are covered by my medical aid (Bonitas) and today almost 2year later I get a call from some lady telling me that I have been handed over for an oustanding amount of R350.91, first of all the dentists office never phoned me whatsoever to make me aware and secondly the original amount on their files is R315.
