Deliver to Incorrect Person and Address

I ordered an item from Takealot and clearly and correctly ensured that the addresse (my mother) and addess (her address) were correct. I received an email confirmation from Takealot to say my item had been delivered. So I checked with my mother and she had not received it. It happens to be that Mr Delivery had delivered to the next door neighbour as my mother was not at home. This clearly violates courier company policy of delivering only to the person listed and address listed on the Invoice. When questioning Takelaot, customer service merely say if I have any queries with delivery to take it up with Mr Delivery. Simply washing their hands of any responsibility. Yet I placed my order with Takelot, they accepted my money and my \service contract is with them. Now they wont even answer my emails asking why they delivered to the incorrect person and place. What if the neighbour did not bring it over
