Mondelez India Foods / Cadbury India — Cadbury personalized birthday Tin box

I ordered a personalizef tin box on 18th July. It was worth Rs 1000. I have still not recieved the product. I have been calling the customer care daily and no one is registering my complaint, they are not issuing refund and they don't know when will the order reach. This is highly unprofessional. The birthday has passed and by now the chocolates would be completely spolit.
But the customer care is doimg nothing, they say we will call you back with information but they are not doing anything at all and are acting as if they are not responsible for this.
Will never order anything again from this company, really bad service. Disappointing
