Appalling After Sales Service

I bought an Hisense free standing 4 plate stove with electric oven from Takealot on 17 December 2021. The unit was delivered on 30 December 2021. The oven on the stove did not worked when I unpacked it. I tried to return, but Takealot revered to HiSense. I tried phoning the *** number, but it continued to take me back to switchboard selection after a few minutes. I then found the support email online and sent a mail. I eventually spoke to Kevin on 11 February 2022. Kevin never apologised for any inconvenience and made promised of which none materialised. I then got mail from Zandile, very unresponsive and her lack of knowledge is shocking. Again promises made, mails unanswered and issue not resolved. I then phoned the 0860 number again on 3 March 2022 and spoke to Monique. Again promises made on how quick the issue will be resolved and since then again nothing happened. I filled in forms, sent proof of purchase and received a number to keep from Kevin #*** on 1 March 2022. I don’t know the meaning of the number, but nothing changed thereafter. The ticket # 441984 was issued to me early in February, it there does not see, to a system in place to follow-up on tickets. The after sales service at Hisense is non existent.
