Pharmacy New Vacoas Mayaram - Mauritius

I am Mauritius origin and has been living UK for over 30 years. I badly needed few medicines and left a list to be quoted the prices. After 3 days I came back and was given these. At same time I accepted that I be sold four of the listed medicines. One of them was a box stating 100 tablets priced at Rs 272.62. At home, upon checking I was shocked to find only 90 tablets. Further I could compare that all the prices are more expensive by a range of Rs 80 to Rs 175. Also the guy never gives a receipt. My total paid did not agree with each priced item either.

I really feel cheated. Could it be that he thinks I am a 'foreigner' so he can get away with 'cheating'.
