Text is blocked and T-Mobile is saying I was spamming

I've been a loyal T-M customer for over 15yrs. I don't have social media on my phone, I don't answer phone calls I don't know, I don't mass text anyone and I've recieved a lot of spam. My phone was "spam blocked" by T-M on 9/13/2023 and I had no idea. I responded to an 8 person group text that I wouldn't attend. This set off the "spam blocker." I sent one other text to another friend right after who never received the msg.

I had no idea I was blocked. T-Mobile never let me know. For 2 weeks I'd been sending texts and responding with NO IDEA I was blocked. When I finally suspected, I called T-M and was told NOTHING of why I was blocked. They said it would be lifted by yesterday, 10/4/2023. It wasn't.

I called back this evening 10/5/2023 and after waiting almost an hour to be heard that I have to wait until 10/13/2023 for the "spam blocker" to be removed. 30 DAYS?!?! Other people who wrote here got 10 days. I'm getting 30?! I've had my account reviewed by multiple people on multiple days and I haven't done anything to get "spam blocked."

I asked for assurance this wouldn't happen again, and got no answers. It could happen to any of you. Beware. I'm switching because it's not safe here.
