VLCC Institute — Request or complain

Sir/ madam,
I'm student of VLCC INSTITUTE. I'M Jagrati Patel. Ï took admission in Diploma in Nutrition And Dietetics from Ahmedabad centre. They charged Rs. 3200 +200 for courier. In my batch students got books in different prices. One o[censored]s got it only in Rs. 824, another one got it for Rs. 1004, another one for Rs. 3200 (including courier). Question is that, there should be equal price for all student. Prices should be same for all. Is this the extra income business study centres started. Why they do this kind of corrupted behaviour. Kindly look into this matter.
