BAD SERVICE ALL ROUND

I bought a Hisense fridge in January this year. I reported a problem with the Fridge in beginning March. Since then I have been battling to return this fridge for a new one. They keep saying they will phone back, but never do. They must come collect this fridge and refund me. Worst service ever from Russells and Hisense. Will never support them again. I paid in cash too.
