Hisense - a sense of NO service

If I could give less than 1 star I would! We bought a Hisense Tumble Dryer through Takealot, especially for my newborn's clothes. 6 months in, the tumble dryer is no longer working (there is no hot air). They sent someone to come and have a look, they got the spare part but it did not work. They said they will escalate it to get us credit ONLY to write on their report that we said we do not want the tumble dryer fixed. Days went by, we called and they said the claim is closed and their policy is to send technicians out 3 times before credit is given. Claim was opened and nobody arrived. Claim was closed, and still nobody arrived. Trying to get a hold of them is an absolute nightmare. When we eventually got a hold of them, they said they need the Takealot invoice and then credit will be given. 3 weeks invoice was sent, the tumble dryer was picked up last week and now when we call, they say have to "escalate the credit!". YOU have got your broken tumble dryer back and have to escalate credit, what a joke! Where is the customer service in all of this?? There are no managers to talk to? We will NEVER purchase a Hisense product ever again due to the non existing service provided, the delays, the poor communication, etc. All we are asking for, is to give us our credit that is due so that we can buy a new tumble dryer. It's winter, clothes are not drying!
