Apollo Pharmacy — fake medicine antibiotics

Address: arun vihar, secor 37, Gautam Buddh Nagar, Uttar Pradesh, 201303

I bought two packs of augmentin duo 625 mg from apollo pharmacy, sector 37, lal market, noida, uttar pradesh, india. O 17-dec-19 mornng i fear that they are fake as it is not giving any relief to both me and my husband.in fact our cough is getting bad from worse even after taking 3 day dosage.
It is very distressing that we cant trust a reputed pharmacy
