Sasol Umzinto

I made a purchase for R60 at the SASOL garage shop in Umzinto on the 12th of July 2019, the cashier used the wrong paypoint device and my purchase has gone of my account as a fuel purchase instead of a normal shop purchase. When i picked this up on my statement i contacted the store and spoke to the manager who took my details down and promised to forward me a copy of my receipt as i was not given a receipt on the day of my purchase. The manager did not contact me back, i then called the store again and he took down my details and promised to contact me back but no response, this cycle continued for the last 2 months and still no response. On the 28/09/2019 i drove down to Umzinto garage ( I reside in Durban and Umzinto is 73km away, the manager was not in, i left my business card and they advised that the manager would give me a call on Monday. It is now the 04 October 2019 and i have not received a call from the manager or any representative of Sasol...I have been requesting a copy of my receipt for the last 2 months now which i would not even need had they used the correctly configured paypoint terminal. Some of sort of feedback would be appreciated. This type of service is disgraceful!
