Should i be pissed if another woman who bad mouths me w my bf messages the following?

'hey chick,
Call me wen u finish work so we'll know what time to pick u up.
**** phone in his bag so u may not get him'.


A little background:
My bf n his friends were hanging out when I got the above message.... Also I have been trying to call him to no avail.

(Two of the women in the group bad mouths me...n one time they told my bf I bad mouthed him... So i try to avoid them wo being rude).
