Usage Report - Duplicate incoming messages and inconsistent reporting

Hey all,

Curious if anyone's had this experience, but noting some unusual activity on my usage report, and curious for everyone's thoughts or if they'd experienced similar.

Roughly 26% of my incoming texts have been 2300 codes, which I've seen are noted to be blocked numbers. Odd thing is these are often group chats, and I haven't blocked these numbers.

Tried to work through this with Techs at Tmobile, across a few calls, and that seemed to resolve an issue with voicemails - while also telling me to run several codes, the purpose of each I wasn't super clear, but appeared to be related to text and voicemail forwarding

Also seeing several code 128s, around 60 over the last several months - which I'd seen referenced as Binge On/Off for video, or incoming texts from an iWatch or iPhone, which is really weird as I don't have or use either. 

I'm also seeing a lot of variation across what's being reported in messages - RCS being counted, and then not on other lines, and also seeing duplicate messages across the same entries.

Same occurred with some calls too - with sporadic reporting, a few of them being recent verified incoming calls from Tmobile customer care team while I was trying to look into these issues. 

Largely, curious if anyone has had similar experiences, and on shared plans or family lines, or had explanations for variations in reporting like this across lines.

Thanks for any info you can provide, and eager to hear the communities thoughts!

Cheers
