Reliance Petroleum — product - petrol - fraud in billing

Fraud in billing. Reliance petrol pump in palayamkottai-tirunelveli highway in tamil nadu. Service is ridiculous and behaves irresponsibly. Our vehicle is bullet electra 350cc with tank capacity of 13.5l and reserve capacity at 3l. Before it reaching reserve we took our bike for refill where first of all spilled excess petrol and second billed us for 11.83l which makes a total of 14.83l considering the 3l in reserve capacity. On asking the workers to fill petrol in a 1l measuring tank they refused and asked to contact the operator. The operator spoke in a very bad manner. We never refused to pay the bill but we demanded they showed that the petrol filling was not fraud. They changed the settings and then showed us the filling after continuous arguments. On further quiring abt the change in settings they refused to speak and forced to make a payment. This is utterly ridiculous. We did verify the petrol volume in an authorised royal enfield service station in cochin. We demand immediate actions from the authorities or matters will be forwarded to the excise and vigilance dept.
