Faulty Dishwasher and bad support services

Honestly extremely disgusted at the services & products delivered by Hisense SA. During December 2022 we bought a brand new dishwasher on Takealot, it got delivered while we were away on holiday, and we only managed to unbox and test it last week when we returned back home. In doing so the machine appears to be faulty/broken as it keeps on showing different error codes or doesn’t work. We referred to the user manual that indicated that one should contact customer support immediately and stop using the machine. As the dishwasher came with a manufacture specific warranty Takealot does not deal with or facilitate the returns/replacements and we had to take it up with the manufacturer directly – Hisense. So, on Monday I send a email to Hisense containing the details of the faults as well as proof of purchase and serial & model number, I received back an automated e-mail with a ticket number. On Wednesday I did not receive any form of feedback/support and I called the contact centre whereby the consultant advised that the claim is to be referred to the Credit department. So off I went sending yet another e-mail with all of the necessary information to the credit department. Once again, no feedback/support from Hisense. On Wednesday I called the customer support again whereby I spoke with a consultant that advised that she would escalate my claim. Thursday comes around nothing happens. On Thursday I phoned again, and the respective consultant advised that the claim was never escalated however she will ensure that it is escalated to her manager in order for us to get a job card for Hisense to come and collect the faulty dishwasher to replace it with a new one. Obviously, nothing happened yesterday, we are yet to receive a job card and all while I’m sitting with a broken dishwasher that I can’t use. It’s really disappointing that one pays so much for a brand new item and then when it arrives it is faulty/broken.
