Group 1 charges

Was trying to find out Why have I been being charged what looks to be two different bills all this time. Why do I have group 1 charges? I have absolutely no group. It’s just me & always been just me since AT&T was Cingular. I feel like I’ve been scammed this whole time paying 45 a month extra for something I don’t have. 
I’m a long time customer & have always stayed loyal  but I’m seriously considering switching providers because this is just a crazy amount of $$$ I’ve been handing over for a long time & I only have one phone. I’m disgusted by this. 
Not to mention how terrible my service has been. Slow, 1 bar …. Sorry for all the complaints but I can’t see myself paying some group charge on top of what I already pay for my one cell … I only have 3 payments left then  the phone will be mine to switch to a more affordable carrier. In todays times I can’t afford no extra crap that I don’t even have. Sigh….
