Indian Oil Corporation [IOC] — Customer mishandling and humiliated in chennai, ashok nagar petrol bunk

Today (01.12.2023 time : 8.30am) i filled fuel for Rs 200 and made payment vide google pay and showed the paid message to the attender.
The attender said he didn't receive the amount, I showed the message once again but he offended me saying that it was the fake message and iam cheating. I showed my bank statement also but they demanded me to pay once again. I refused to pay they made me to say for more than 20 mints and treated me as fraud person in front of other customers. After 25 mints i request them once again to check after checking they said late credit and let me to go. I am totally disappointed, humiliated and took decision, not to visit Indian oil petrol bunk any more.
