Ecom Express — Product not delivering by delivery service

On 12th march i order this product awb no ( [protected]) from shopsy which is another branch of Flipkart.
so on 20th march my product delivered in my city delivery boy called me for address he said ( i will come at evening) but he didn't came and even didn't call me back, till 22 march 3 attempts was held by delivery boy but he never call me for delivery concern, when i call to ecom express costomer care they said my now product have ofd lock, i searched for this i found nothing about it, and even Flipkart also refuse to say about this ofd lock they don't know about this .
my product is in my city and they don't deliver it to me even they refused me to tell the location, contact no. of delivery centre and also said even if they provide me location they will not give me my product, they say now my product will not be deliver to me and cancel it by them .
its a clear fraud by ecom express
