Petrol Attendant stole my money

Poured petrol at the sasol k101 on old pretoria rd, midrand yesterday 15/09/2017 to fill up my tank. was assisted by 3 petrol attendants, i thought it was rather strange at the time but yet again thought it was great customer service but i was wrong. once they were don, inserted my key but the petrol did not reflect in my car. made a u turn back to the garage to speak to the manager. was told he's not in and should come back tomorrow morning, 16/09/2017 or take my car back to the dealership as it might be faulty. told the guy that's impossible as the car was brand new. 5hrs ltr i go back to inquire again, luckily this time i got a hold of the manager, Mr Pitso. he wasn't much of an assistance and gave me attitude and told me, my car had a problem. asked to see the cctv footage and their system and how come their system generated a receipt without the plum actually pouring petrol in my car. let whilst still arguing with him as it was late in the evening and was driving with my daughter. drove up the road and ended up filling at an egen garage which eventually did fill up the car. took pictures of before and after and kept the receipt from sasol k101 and called the head office to report the matter. was given a ref number and cc'ed in the email sent to the complaints department this morning, to go and open a case a of theft against the fuel attendant, Standford and his manager Mr Pitso. they promised to investigate and revert back asap. i will given them 24 hours, if i don't receive any response, i'm taking this matter further. at this point im not fightingabout the money but more about the manner and the principal in handling this matter. and whilst at it, the manager fighting me in front of my 3 year old daughter!!!!! i will not be victimized and let it go!!!!
