unsatisfactory customer service

I bought a double door fridge and after 3 months my food was getting spoiled inside the fridge. I complained at Defy and they sent a technician who then said I need to contact takealot as the PCB of the fridge isn’t working. I have contacted takealot for the past 3 weeks with no action. They just send an email enquiring whether the unit was picked up. I have responded several times asking them to notify me inadvance when they will be sending people to uplift so that I can clean it but till today I haven’t had any response from them. I m angry and disappointed as I have to throw away a lot of food because the top part of the fridge isn’t working. Can someone from takealot please attend to this query
