Horrible experience, went to fill up gas May 25th at approx. 5:00pm. Told the lady on the counter $20.00 on pump 5 and she said okay. However, she didnt give me a receipt which not too much of a big deal. Went to pump 5 where I was parked to fill up gas and no gas pumped. I thought maybe this one isnt working I'll let the employee whose name started with an M; so we'll call her Mrs. M., know that it isnt working and two switch me to pump 7 since it was just right behind pump 5. Went inside to notify the lady that the pump wasnt working and she stated that the system said I did pump it. I told her to double check because I had only been out there for less than a minute and there's no way you pump $20.00 worth of gas in less than a minute. She answered in a very rude tone saying "no, you pumped it and that's it." I asked the lady to dou le check and she refused. Because she was refusing to understand I spoke with the other employee who's name was amy. Long story short they printed out the receipt and the receipt Mrs. M stated that proved I pumped gas was dated May 25th, 2020 @4:00pm. In the 30min of me discussing with them and trying to help them understand what had happened; I was the only customer that payed cash for gas. When Amy pulled out the receipt of cash payments for gas it showed that Mrs. M put in the system $20.00 cash on pump 12 which was 2 rows over from where I parked. And even after figuring out where the problem and who had made the problem Mrs. M; who's an older lady, refused to give me a refund or let me pump gas. When I asked for the Managers phone number she also refused to give it to me. This is by far one of the worst customer service experiences I have had. Not only did I lose $20.00 but after they found out who was at fault they refused to take responsibility and make things right. When they did call the manager, Mrs. M said that the manager told her not to refund me or give me gas on a different pump. I will go in tomorrow to speak with the manager and have him review the cameras so that he can be assured I'm not lying or trying to "steal gas/money" according to Mrs. M statement. After speaking with others they said that this ampm arco gas station is notorious for not admitting their mistakes and people always getting their cards overcharged and or the employees not typing in the correct pump number. Avoid this gas station at all cost not worth it. read more
