Cafe Coffee Day — Bill not being received and charged higher than normal.

Hi, today in Thane branch of CCD in panchpakhadi, I ordered a garlic bread, a hot chocolate, and a regular late. And I was charged 853 INR. I asked for bill, and was given an excuse that the machine isn’t working. I asked to give me a photo of the price on the screen, I was told that it already went. I asked for a manual script of bill. I was still not given one.
Please look forward into this. This is hard earned money, and being overcharged for something like this, and denying request of bill is highly unacceptable and highly below standards of reputation of CCD
