Dishonest by charging double and returning money

I ordered a pizza to delivered to my house. The driver (Ian) charged me double, he advised that the payment did not go through the 1st and asked to punch again. I went to get phone to see if the transaction took place and showed him that he charged me twice. He told me that he has reported the matter and I will be re-reimbursed or reversed within the hour. This never happened. I went to the Debonairs i ordered from the following evening at Vaal Mall. Got such a poor response from the manager, cant recall his name. He advised he cant help me I must bring him my bank statement. He never bothered to take my details to follow up on my allegations against Ian. The Atm did not have print outs for bank statements so I came back later in the week. I was then referred to another manager (Maria) she accepted my bank statement and did her own investigation and found that Ian did charge me double and worse he never reported the incident as he was even billing people with the machine he was not supposed to us which actually belongs to fish away. So now my money was not accounted for. She took my details and advised my problem will be resolved by Monday which you can take a wild guess was not resolved. Its 3 weeks later and I'm still cheated out of my money by Debonairs. No one bothered to call to even apologise. Its not about the money but the principal behind it. People work for their money, so if you cant respect your customers you are in the wrong business.
