Worst customer service

I purchased an iPad 6th generation via Takealot in June. It then refused to power on during October (about 4 months). I logged a return and dropped it off personally. The individual I dealt with at the warehouse examined the device and the contents of the box and agreed that everything was in place, no accessories missing. I also left them with the pin code to unlock the iPad should they get it to power on again. Later that day, I received an email requesting that I remove the device from my Apple ID to avoid cloud lock issues, which I promptly did. It has now been more than 2 days and each time I enquire about the status of the return I am told the same things: accessories are missing, and they need my Apple ID password. This is pathetic service. Had I known I would have this much trouble I never would have purchased it through Takealot. Once this issue is resolved, I fully intend to deactivate my account and no longer make use of this service (as convenient as it may be) because of the extremely poor customer service I have received.
