TOTAL LACK OF TECHNICAL EXPERTISE!

I recently acquired two Ezviz Husky C3W Security Cameras from Takealot. It did not take long to realise that Takealot does not have any Technical Expertise on these cameras to assist their Customers with camera issues. When I contacted Ezviz South Africa, I was told by their Techincal EXPERT, Disney, that he can not assist me and that he will have to get an ENGINEER from CHINA to contact me. I now beg the question;- how can Takealot sell these products and how can the Consumer Council/Commissioner allow products like this to be sold in South Africa, with them having limited technical experience, thus frustration Customers immensely
