Aavin — Was charged for 5 flavoured milks but got only 4 - when asked, was told that I am lying

Extremely pathetic customer service. My family had initially asked for 5 flavoured milk but then changed the mind and said they want only 4. However was billed for 5 and we noticed that only after getting home. After 3 days when I went to ask at the shop (as my mother is quite old and could not act on it earlier) - the guy was arguing stating that I could have taken 5 and creating a false story. I don’t understand why someone will create a fake story over Rs 30. This is not going to make or break anything for us. It was about customer service - we were wrongly charged and we expected the shop owner to take that into consideration. Was a horrible experience dealing with this person at Besant Nagar (near the depot).
