You are given an amazon food product review and its polarity (positive or negative). Your task is to answer "True" if the specified sentence and its polarity match; otherwise, answer "False".

After a few uses, this powder spoilt a cake. It has lost its raising power. It is still well within the expiry date and the container has been kept closed and in a dry place. Avoid this one. I plan to ask for a refund.
Polarity: Negative
True
