Horrible dental services

If there was a negative I was going to rate it as such. I went to do teeth fillings at their Centurion branch , two weeks after the fillings the teeth were breaking porcelain pieces remaining on my food as i eat. I went back there and told them what was happening and to ask her to fix her mess, ,i did not get no apologies whatsoever and she was just standing there asking me to show her which tooth is broken when really it was just very clear which one it is (my front tooth) , she then did another very quick fix on it resulting with me walking around with a broken tooth after 2 weeks of it being fixed. Now as i write this the other teeth she was working on also have dents on them. Im totally heartbroken and disappointed when i think of how much i spent wasting funds on my medical aid paying for such horrible services.
