Money issuses #RANT

Soo im on my S/O phone bill plan with his 2 older brothers & sister,, well we didnt have unlimited internet & we all had to share data. Last month i went over the data & i guess i was the one who spent the most gigabytes.. Well his older brother who's phone is the head phone texted everyone but me saying that i had to pay 120$ extra plus the amount of our phone bills,, i was sooo furious that everyone knew but me! until my S/O told me when he got home,, it wasn't for his family to know how much i had to pay, i was the one who went over i felt like he could have texted me & tell me personally & not tell everyone else... Sorry girls i just had to rant
