damaged unit

Fridge was assessed and fault was determined on unit, thereafter no response from any person at the call centre regarding exchange and a personal trip had to be made in order for something to be done,when they finally managed to get an exchange, courier company damaged the new fridge and Samsung prefers refunding instead of exchange whereas I cannot afford to replace the fridge, I'm totally and utterly disgusted to own any Samsung appliance! Fridge is still under warranty and proof of purchase was provided on numerous occasions as well.
