Charging twice and not refunding

I purchased something from Edgars Sandton on 25/10/2015.<br> I have been charged twice, Floor manager said I will personally make sure they are going to refund you, Clement, gave me his cellphone number to contact him just in case there is any problem. I tried to contact him but he doesn't answer the phone and he doesn't even reply to the sms.<br> <br> after my last complain on hello peter they contacted me and said we will refund you within 48 hours. that was last week.<br> very disappointed!!!
