Dissatisfied/Angry Customer

I'm writing this because I have not received any assistance from Pick n Pay hyper Maponya Mall. I bought a washing machine that gave a problem in 5 days and I called their customer service and explained my issue I was told to go back to the store and provide the receipt then I did that. When I got to the store I was told they'll send an email to the supplier/manufacturer of the machine Midea which they'll send a technician who will come look at the machine. That was last week and was told it'll take 48hrs until today 4 days later no call no technician has come and I'm sitting with a washing machine that isn't working. This is unacceptable service I demand you come take your machine and give me my money back. I called your customer service again today and it rings with no response. I'm not sure if this is how you treat your clients and run this money making seem. I want my money back.
