GROSSLY OVERCHARGED!

i had a wrist injury beg. August and needed a wrist support ,so i was told by the attending Dr at the hospital. I said i could get one at Dischem but then was told that they had one in stock so they came and fitted it. and i had to sign a form to say they had supplied a support. i was not told the cost of the support at any such point. I left the hospital as they said there was nothing yet to pay. My Medical Aid did not pay due to my savings being depleted as per the medical aid statement i recevived. i now almost 3 months later received an account over WHatsapp from this company but the aco**** is in the name of Berkowitz van niekerk, which is way way more more than a similar product at Dischem and clicks, wihch is only R 165. This company has charged me R1031,00!!!! THIS IS AN ABSOLUTE RIP OFF AND SECONDLY THEY DONT TELL YOU ANYTHING FIRST HOW MUCH YOU ARE BEING CHARGED!!
