Broken base

I have bought a restonic emerald 152 base set at nelspruit on the 2nd of April 2016,the base is broken took it back to the store on 17th of December 2017, the manager did not assist in any way he said the supplier is closed must take bed back and came back in January I left the bed at the store due to frustration, my husband sent an email on the 4th to Margaret Wilby at head office and the reply was your complain has been send to senior management for further assistance, I had sent an email on the 10th had the same reply with reference number 023987-01. I phoned today to check if there's any progress I was told that they did not get any feedback from nelspruit, this is so frustrating
