Dis-chem ****** a 72 year old lady.

Dis-chem Rand park ridge just charged a 72 year old lady R 270 for a flu shot. She has Discovery medical aid but Dis-chem charged her almost double the price because they pleced the wrong code for the claim from Discovery. She paid the money but found out from her broker that Discovery does pay for over 70 year people. Now Randpark ridge Dis-chem refuses to return her money and fix the mistake they made by claiming for over the counter medicine. They must have entered the code for a flu shot. They must contact *** or contact her ***
