refund

Good day

I would like to complaint about the owner of the pharmacy Mr Mkansi at Park Central Pharmacy at Johannesburg. Last week Thursday I went to the pharmacy and asked which tablets can I use for the heart and they advised me to take the carlog I bought them. When I got home my daughter advised me to go and see the doctor before using the tablets and when I went to the pharmacy for refund I found the owner and was very rude that he wont refund me and the tablet where in good condition the box was sealed and the slip was also there and their number is ********** 730

Please assist

Thanks Daisy ********** 677
