Issues with them claiming from my medical aid

I ordered contact lenses. The lady at the counter then put the claim through on my medical aid FOUR TIMES!<br> They reversed two of these, the third which I had to contact them to sort out.<br> Lennel Somers then tells me everything is fine, and I receive my discovery Claims history and I can see that the claim was put through FOUR times, but that the three mistakes (made my VISION Optometrists) had been reversed.<br> I'm assured everything is sorted.<br> Then I receive a bill in the mail for the contact lenses I have already paid for!<br> Absolutely ridiculous. Would not recommend using this company. Their financial department and billing system is just a HUGE headache.<br> It will now be the third time I have had to go into this Optometrist office just to settle this ONE transaction.<br> Mistakes on billing is not acceptable. Very unhappy customer
