****med into paying more than I should in skystop convenience OR Thambo

Today around seven in the morning I passed by the garage engen skystop convenience to fill up I had R100 , I told the petrol attended (ntsako) to full up my tenk with R100 he poured R300 and he said it was my fault he asked me if I said R300 and I told him yes. He called his manager the asked what must they do because they already poured, I told them to drain it out they don't want they said no they saw me communicating with the attended so I must pay , even wanted me to leave my phone go make a plan for the payment. They forced me even called a police officer to Threaten me so I pay , the said I'll go to jail if I don't pay and forced me to pay
