Just NO support and service

I have always had good shoping experiences on Takealot until the first big item I bought in December 2021. I RECEIVED THE Hisense tumble dryer ON 12 DECEMBER ON 23 DECEMBER THE REQUEST FOR RETURN WAS DENIED I WAS TOLD TO CONTACT THE SERVICE PROVIDER which I did and we were on leave for 2 weeks. So the machine was not used a lot. On 4 January the PC board of a brand new machine was replaced. It has never worked properly. It took 6 hours to dry washing of 6,7kg it was a 8kg machine. I have been complaining ever since to Hisense. NO SUPPORT other than ticket numbers and sending the technician to ask the same questions everytime. Last week I received an email to confirm my refund / credit that was done in April, not where to look bank or Takealot. I called again and the agent said the system show a refund in May constantly interrupting me. After a long discussion they said they will collect the machine on Friday when I am home, but Thursday afternoon the courier arrive and took the machine back. When I called Hisense again, I asked the lady from Hisense why they did not keep to the Friday arrangement when I would be home she asked me why I want to be home for them to take the machine. My refund was suppose to be back with Takealot YESTERDAY according to Hisense and they would have called, NOTHING NO FEEDBACK NO PHONE CALL. I am so tired of this issue as it has just been painful from the date of delivery and as the customer I am treated like some idiot. I tried everything, from nice to rude from obnoxious to professional there is no difference. Neither Takelot nor Hisense has any interest to assist me. Customer support and service does not exist at all. Everytime the same questions and reference numbers. You should seriously consider removing the 30 day hassle free exchange, it is the biggest lie on your website. Then emails to ask me again about how you can assist and pictures of the item and I need to request a return. Its hopeless. Totally hopeless. How do you select providers as Hisense is not adding value at all.
