Unprofessional and deplorable Service

I have received the most appalling customer service from Hisense South Africa I logged a call a week ago for my washer dryer. Unfortunately I didn't have my receipt so the agent logged it as an out if warranty service. I was called within a few hours for a tech to come out to check the machine. Fortunately for myself I had located the receipt and was therefore covered by the warranty. I was informed to relog the fault as it fell within the warranty. Unfortunately this is were my battle has begun.I was informed like previously to expect a call from a technician . Two days later and had to call again and only then was the fault logged. I was then called by the third party company who informed that a tech will be out to me the next day and couldn't confirm a time and should just wait for a call from somebody to confirm. As I desperately needed the machine sorted I then booked myself if work and waited the entire day for a call.By 3pm I called Hisense again only to be told they not sure if th e tech was coming out.After threatening to go to social media they hurriedly sent a tech at 5pm.Tech calls me so confused as to whether I need my TV or washer repaired Eventually e arrives and informs me he has to take the machine away.He asks me to sign paperwork .I then asked him for my copy ,He informed me there's nothing he can provide me with.I then ensured I took a Pic of his paper work . He assured me I will have feedback the very next day.I received no feedback or call from Hisense. I hen called two days in a row eventually I was told the machine was beyond repairs it will be replaced and the old machine will be delivered back to me.I can only get a new machine if I take the old one to were I bought it 3hours later I get a call for a 3rd party company called Master Care Auto and a lady by the name Heather informed me that the machine is being fixed .After explaining that Hisense had in fact confirmed i would receive a new machine,she became aggressive and told me Hisense made a mistake and there's no such thing. She continued to scream and say its not her problem I should go and find out from Hisense because she already had ordered the part .She informed me she didn't need to listen to me and refused for me to escalate to management and proceeded to cut the call.I yet again called Hisense who then again confirmed that the machine is in fact being replaced and promised to escalate the matter of the ladies unprofessional behavior. I was assured by dayend I would receive a call for the old machine to be delivered so I could get my new machine. The entire day passed with no feedback. Today I have called Hisense twice and I am still waiting for a team from management to even reach out as it seems no matter how many times I contact customer care,Im given the same answer but with the resolution. I have successfully had a machine replaced from LG two years ago with no hassle. I will never purchase from Hisense again as clearly the product is of inferior quality as the machine didn't even last 2 years The are highly *********** and have not sense of urgency. The lies and treatment of clients are deplorable. It seems like if I were to.pay out of pocket they were quick to respond but now that the onus lies with them ,I am given a run around. The machine cost me in excess if R8500 and it seems that customers hold no value to them
