Guys please hear me Outta

Im honestly so confused and weird out rn.
I know it's long but please bear with me......and tell me if I did anything wrong here! This is just part 1 of the story. There's another too which is honestly a very hilarious and dumb accusations on me.

So here's the thing, I feel like some of the girls (a certain group of friends) in my dept have been trying to Target me for anything and everything by making it sooo serious when I don't even mean it. (In our department gc).

Few days ago, 3 of my classmates(including me as well) were messaging each other regarding how one of teacher keeps changing the test date. We finally met to the end of our conversation by confirming the date of the test. Then suddenly one of the gurl texting accusing us of "spamming the class gc" as well by saying, "you two are the only one texting here, stop spamming and go personal". Which infact were 3 of us and NOT 2.
THEN, when I replied to her saying, "gurl, we ain't spaming, we're just trying to confirm the date of the test and btw this gc is soo dry so chill.... we're not even texting 24/7"
Then she ignored the Test date confirming part and started ACCUSING ME OF "ALWAYS BEING ONLINE 24/7" . I'm honestly amazed, like how did she know I'm online 24/7? Which infact I've been having a very busy schedule due to my practice which ends at around 6pm in the evening. (Classes starts at 8:30a.m) I hardly even use my phone nowadays and she directed accused me of being online 24/7. And what's more hilarious is that the gc was made just 24hr ago.
Then after that some of the other members came, chit chat happened then u know what!!! She herself started texting sumone in her own mother tongue (which most of us don't understand) for like more than 10mins. So imagine, she accused us of spamming meanwhile look at what she herself is doing! And also! She accused me of "trying to take the CR (class representative) role just because I send some text in the OFFICIAL class gc regarding correction the question the other person send and as well as informing my minor subject mates regarding test and notes checking. (Our CR is of diff minor subject)
