Safetab Life Science — Tablet expired before the date

Address: Chennai, Tamil Nadu, 600044

I bought 'Rosutor Gold' tablet at Medplus Chromepet, manufactured by 'Safetab Life Science' Pondycheri. Find the attached photograph of the tablet. The tablet bought on 1st week of January. My mother already consumed 6 tablets. When i try to launch complaint against the company, i could not able to find the mail id. How the reputed company and the seller can sell the worst quality of the tablets. Suggest me where to complaint about this. P.Yuthsitran [protected]@gmail.com
