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

I use my texts for business. Yes I send many texts to many different numbers.  With work information for legitimate jobs/events many large jobs with many skilled people and must fi d them in a short period of time. Never send links of any kind in the text just job information and ask them to contact if interested. Most of these people are looking for these texts and answer asap. Never had this happen before with my old LG one. But I switched to top of the line Samsung 23S Ultra and BAM, First time I send this information texts, blocked.  If anyone actually looked at the text, they could tell that it is not spam.  They say they look at what gets blocked. They lie. Many People anymore don't want to do their jobs and don't put in effort to do the job properly.  They say my block should come off on Aug 24th.  The event runs Aug 20-23.  They killed my chances for me finding the people needed for an event that draws over 10,000 people. They lost money for many people.  May decide on a new provider as the supposed tech rep put a ticket in and said that it should be looked at within 72 hours but she will not be in to update me until the 23rd. (The last day of the event).
