Medlife — medicines supplied

I placed an order for medicines on the 4th aug being assured 18% for my medicines worth almost rs 1500, i recd my medicine yesterday. With the bill of only 16% with not all the approitate medivines and paid by card the amt of 1350. I phoned c care this morning and was told that the amt paid was less and hence the discount was less. Couldnt i be informed by sms about the 3 bottles of 250 ml of dulphaac was not at hand as so a 150 was sent instead. Being a senior citizen if feel cheated and lost trust wih medlife after being regular buyng my medication from ur pharmacy. Kindly look into this matter and refrain from these hardships for seniors where every amt counts. Mrs tency gonsalves
