[Resolved]  Flipkart — About making my home address as non serviceable area after giving service previously

Hi, I ordered a amez back cover for my phone order id being OD[protected] and tracking ID being FMPC[protected].
But the courier service has made my address as non serviceable area and it is saying to collect my product from their pick up store...
But my question is that they have earlier delivered services to the same address.
Now how come a courier company can change my address as non serviceable area and harras me to collect it from the pick up centre when there is a home delivery facility available.
