Poor return policy for faulty iron

Purchased an iron for my parents, it stopped working, returned and replaced, within 3 months and 2 weeks it's stopped working. Contacted takealot they say the 3 months is up and we need to contact the supplier but no details provided. We paid over R2500 for the iron and it was purchased from takealot. Why should we have to contact the supplier and how do we do that anyway? The box also says 3 year warranty. Poor return policy and bit unfair considering the circumstances.
