Worse service offered

What a shocking experience at the garage the put the wrong amount and when I want to swipe the guy tap the wrong amount again when I started complaining there comes Thabiso very rude he said the guy he is training and I must understand then I ask to speak to the superior they said he is eating that I find it as a story then I went to the shop inside to ask for the supervisor luckily he was in the shop not eating I waited for him he took his time ofcose John I left I had to call the manger maneger was not there I speak to Lena assistant manager she was very professional and experienced ofcorse and she transferred me the maneger I think that garage should be closed or only the maneger and assistance should be working there
