Medplus India — laktrum powder box seal was broken

Address:

560068

Hi, i purchased one product (Laktrum powder) from medplus store at no.88, 14th main rd, sector 4, hsr layout, bengaluru, karnataka 560102. But when i opened the box, the seal of the box was tempered and then i contacted the store for replacement. But the store person told it is not possible. Please help me. For your kind information, the product is for my kid and we have not used it as well. Store person does not believe it, do you think i will give the product to my kid which is exposed. If anything goes wrong with my kid who is responsible.
