Baskin-Robbins

Iam Dilip from chennai (India) I just visited baskin and robbins-kodambakkam branch. I have ordered for black currrent milkshake and the lady working there added just one scoop blackcurrent and a tea spoon vanilla ice cream and milk for preparing the shake. But to my knowledge as iam regular customer to baskin aand robbins two scoop of wat ever flavour selected should to be aadded to make milkshake. When I asked her the same she was so so rude in answering me back. Service is worst. Please take necessary action. Attached bill for your reference. You can cantact me - +91 [protected]
