LG SOUTH AFRICA BAD CUSTOMER SERVICE

I purchased a LG side by side fridge/freezer a few years ago but after a few months the freezer door started rusting and they replaced the door no problem under warranty. Now a few years later the freezer door started rusting again but this time much worse and this MUST be a common fault with this model yet LG has not done a single thing to assist me with a replacement. In fact they keep replying to me with a reference number and this same correspondence has been carrying on for 8 months now but absolutely no mention of their intention of replacing the door. I am certain that if LG International values the integrity of their appliances they would ensure that this issue is resolved with immediate effect thereby saving the product integrity and ensuring customer satisfaction.
