EXTREMELY BAD SERVICE

Trying to get a repair out of Tevo is like pulling teeth - 6 weeks in and am trying to resolve a part which was returned to me broken. Client services says to contact Takealot - Takelaot is a big company and without any relevant person to contact it is a very difficult process to hope for anyone knowing what I'm talking about. This person who is meant to be in customer service refuses to actually just find out where it is and get it resolved instead of continuoulsy just telling me to contact Takealot. Obviously, I have done this but cannot get any answers so surely TEVO should investigate to get it sorted out. Afterall - this is because of a faulty unit which needed to be repaired under warranty, and which I paid for the repair. This is not a favour. I find the lack of interest absolutely disrespectful and completely unacceptable. All I want is the part back so I can use my unit. I don't really care who does what - just take responsibility for following up and ensuring I get my unit back?
