Parle Biscuts Pvt Ltd - Worm Inside ParleG biscuit packet

We have purchased Parle G (***g) Biscuit packet from Big Basket on **/**/****. (Order no. DX-MHO-********-******). When we open the packet my wife started eating those biscuits without knowing there is worm inside. Same day night she suffered from vomiting and stomach pain (we thought its happen because maybe she eats something wrong from outside or because of antibiotics she is taken for tonsils). Next day morning when again she started eating that biscuit she found a worm inside that packet. So we thought maybe outside worm come inside the packet. But we surprised when we found worm again inside the new packet. This is the worst case of quality and trust on Parle G which we have before we born.
