What does a person need to do to get help!

This has still not been resolved. The unit was collected last week and still Hisense has not updated Takealot with details of the collection. I have only called Takealot once and they have been in touch with me with feedback everyday. Last feedback received was Takealot this morning is they will need to wait for Hisense to confirm receipt and provide the final documents for them to process a credit. They reached out to Hisense this morning and awaiting their feedback. I didn't have to call them for this feedback they reached out to me. I have had to call Hisense call center everyday since I've this query and I'm really scared because in have so many Hisense appliances and if this is how you treat your customers then I'm really afraid. You contact center agent hung up on me again this morning. Is this ever going to be resolved? what do I need to do? Please can someone help me!!!
