The word “advice” is an uncountable noun in English and does not have a plural form.

Therefore, we do not use it with the words “a/an”, and we cannot make it plural by adding “-s”.

We can use some or any with uncountable nouns to express an unspecified quantity. For example, “She didn’t take any advice.”

Or we can use a word like “piece of” or “bit of” to make it countable. For example, “She gave me a piece of advice.”

So, the sentence should read: “She got into trouble because she refused to listen to the advice given by her friends and relatives.”
