3 year guarantee expires after 351 days

Hi Peter, I wrote a review 2 weeks ago about Takealot's pathetic system. My daughter bought me a Brabantia kettle with a THREE YEAR guarantee last year in April. End of March this year I contacted them, because the bottom has started to rust. They told me that 351 days has passed and the guarantee is not valid any more!!! The day after I wrote to you they picked it up, but has now returned it to me. They insist that the guarantee has expired.
