Pathetic all around.

I went to Nudental for a check up just to make sure everything is still fine and happy. I had no complaints or issues I just wanted my mouth checked to make sure everything is a-o-k. The doctor said I had a few small holes she'd like to fix. Again, I had NO complaints and did what she said because what do I know I am not the dentist. After having the holes fixed, one I was unable to eat because of sharp shooting pains in my teeth when I just touch food, not even chew. Two, my back teeth are now so sharp that if I don't chew carefully I keep biting chonks of my cheeks, fun right? So according to this doctor my medical aid where to pay for everything I do not have to worry about the costs. Few months go by and I get debt collectors calling my father about a bill with them. I get in contact with them, immediately settle the bill, immediately send proof of payment and the lady I spoke to said no problems they'll take it from there. Now, I have debt collectors calling me every single day for this account I paid in full MONTHS ago, AND now I'm getting bills of over R1000. This is pathetic. I have to pay a fortune to another dentist to fix what she messed up. My teeth don't pain anymore but I still cant without eating a piece of my cheek. And as a side note the dentist I saw was so mean to her assistant even I got uncomfortable being in the room.
