Lukoil review: unethical behaviour

This gas station doesn't even deserve one star...I stopped there to by low leaded gas using my credit card and after I finished pumping and paid for it. I noticed on the machine the total price seemed too high. On top of it, the gas pump machine didn't even print out my receipt and I had to go inside to retrieve it. The elderly man that I spoke to said I must of accidentially hit the high leaded price button and it automatically changes. I said No I did not, but he didn't want to hear it! He was quite nasty. In all my years, this had never happened to me. Be very careful at this station and buyer beware! Yes, I would love a refund!
