Horror treatment

Went to have my ears syringed at Dischem clinic at Liberty Midlands mall. To start she put boiling water down my ear. Then wen she put the syringe in my ear she banged it twice which was terribly painful. I asked if she had managed to clean my ear - she said no and told me just to put in more drops and it will come out. No surprise that I did not want my other ear done. I wrote to Dischem to tell them that my ear is very painful. I got a feeble reply that they are sorry. I feel that the least they could do is refund my money for a horror visit and pay my doctors bill. They have ignored 3 more of my emails It is almost a month later and I still have earache. I am 77 and have no medical aid.
