Caltex Amanzimtoti

Almost a month now since I put in R500 petrol at caltech Amanzimtoti. The card machine declined and they took another machine from FNB that did go through. After numerous bank statements and emails I am still waiting for my R500 to be returned to me. R500 is a lot! They are *****ing from customers and I will not rest until I have my money back!
