Kaak Service and **** products

I bought a bed at Lewis store in Witbank KG mall 3 months ago. The bed is like titanic ship, the mattress cover has torn. It does not look like a new bed anymore. I have called the store several times but I have not got any help. I contacted them last week Tuesday they promised to call me during the week. This week I called again I spike to the lady called Dorah, she said the manager (Moses) is on leave, she will speak to acting manager (Lindiwe) to call me, Lindiwe never called me. I called again on Tuesday, Dorah answered and I asked to speak to Lindiwe, she promised me to give her massage to call me, still she never called me. I called again today I found Lindiwe, she told she is very busy with trucks she cannot help me, she said she is the only one who receive the stock. Lewis does not take their customers serious and your products are ****. Please refund me or give me a proper bed.
