Poor customer service on Big Appliances department

On 2020-07-31 I bought 18kg Hisense model WTY1802T automatic washing machine that have electronic fault of water overflow. I paid R7 090.00 for the washing machine cash including delivery and the washing machine was on sale. I reported the complaint on 2020-08-04 and to this date they send me from pillar to post for collect &exchange of goods and they even ask if I cannot transport the washing machine to the Store. On 2020-08-13 I made a follow-up on the complaint and they couldn't find my complaint form and no one could account. I am still waiting for collect & exchange of goods and they keep on giving me empty promises that we're delivering tomorrow.
