KIC Appliances let down by bad after sales service

I bought a KIC fridge from Game Stores a while ago. Sadly the Salad Basket and Door Shelf broke, so went out to get replacements.

Game suggested going elsewhere, elsewhere could not help so I contacted KIC directly. All went smooth, select the part off a schematic, get a price and pay, then, silence, nothing, no feedback.

One month goes by, send a mail, told to please wait 2 weeks. 4 weeks go by, another mail, told again to please wait 2 weeks. 3 months later, no feedback, no parts, no tracking number.

At what point does one call it unacceptable that payment was made for a part that is not supp****?
