Horrible customer service regarding the re-call of the faulty Gizzu Powerstations

I am shocked with the pathetic service received from Synech to date. This is regarding the Recall of the Gizzu Powerstations that are a safety hazard. My unit is one of the faulty ones and I filled out the form for them to Replace my unit. A certain individual responded and gave me an option of them picking up the faulty unit and delivering the new unit and I agreed to that option. He then responded and told me I should send it back to Takealot as it will be easier and that retails will get stock first. I responded that I cannot return to Takealot as I bought it from Builders and it was delivered to me and that is what I want, I need it delivered to me. I got no response; I then sent another email to follow up and still no response. I will not be inconvenienced for an issue that is not mines, I paid full price for a product that was to be safe and the fact that it is a batch that was not safe is not my problem, Please could someone with better customer service and professionalism, resolve this for me. I want tthis faulty unit picked up and my new unit delivered to my door as is what happened with this unit.
