Ambal Indane Gas Agency,near Aaryaas Hotel, Saravanampatti. — Collecting excess tips for Gas delivery

Ambal Indane Gas Agency Distribution folks are compelling and allegedly behaving bad and talking vulgar words if we refuse to give tips. They collect Rs.650 agains the bill amout Rs.616. If we question, they threaten us as they will send back the bill to agency saying "Door Locked". Their behaviour is also worse. Please take remedial actions to stop paying excess tips and warn the delivery folks to behave humble and decent to customers. Nirmala INdan Gas Consumer Sivasakthi Nagar Saravanampatti, Coimbatore
