3 months still waiting for base for my bed

On January 2015 I bought a bed (base and matress) from Russells in Daveyton mall and a week later the base broke. When i was on leave the first week of February i went there to inform them that the base broke, I was then provided with a claim form to complete and two weeks later an assessor came to assess the damage and confirmed it should be replaced. I got an sms confirmation that a new base had been authorised with a ref number and i went to the store and they told me that their warehouse will place in a new order for the new base and will be in touch with me, I have since then been waiting. From February to May still waiting for a new base!!! Can someone just do something???
