Poor service at Total Garage - Hazyview

I went to Total Garage - Hazyview in Mpumalanga to fill up my vehicle with fuel. I filled up my vehicle and I bought some food items inside the store which came down to an amount of R1043.39. I used my card to pay. My card was swiped the first time and the transaction was declined due to network problems according to the cashier; my card was then swiped for the second time using a different speed point machine which went through successfully. I drove off afterwards. About 3 months later I decided to go through my bank statement because something was not adding up; I came to realize that the payment which I made to Total Garage appeared twice on my statement. I contacted the branch manager to inform him of what had happened and I also emailed him all the supporting documentation to validate my claim. The service I got from him was so unsatisfactory to such an extend that I had to drive all the way to garage to try and recover my money. I was not able to recover my money from him so I escalated the matter to Total South Africa. They acknowledged my complaint and gave me a case number. It has been a month now and I have not heard anything from Total South Africa regarding my case. I am very unhappy with the way Total has dealt with this matter. I cannot comprehend what is so difficult about resolving this matter. I has been 3 months to date since I initially lodged my complaint with the branch manager at Hazyview and I have still not recovered my money. I would not recommend Total to anyone after my experience with them.
