* Disculpa pero fue un errol q molque mal: This part is mostly in Spanish. It means "Sorry, but it was an error that was done wrong."
* no quiero ese articulo: This part is in Spanish and means "I don't want that article."
* disculpa: This is Spanish for "sorry."
Putting it together:
The person is likely apologizing for sending the wrong article or for some other error, and they are saying they don't want the article. The phrase "errol q molque mal" is probably a nonsensical phrase they used to describe the error.
A more understandable way to say this in English:
"I apologize, but it seems there was an error. I don't want that article. Sorry!"
