suspended out going messages

The situation is this: I have been banned 4 times in the last month. No details given to me, never told I'm locked out from sending texts. I've called many times. Every time the tech person says they will follow through and at some point they drop off from following up and I'm where I began, locked from sending texts. They have tried to delete my number and reinstate it to trick the system and that did not work. I filled with the FCC website and I have only gotten the thanks for adding a grievance. The site is odd, what I want to complain about is actually under receiving spam vs saying I can't send messages. There is a box to check eventually. I sent a follow up email to the email account asking for more information and follow up and nothing happened. Best I know there is no way to talk to an engineer. Good luck finding a tech person to honestly follow through. At this point they say change my number and that's not an option. I may change my carrier and port my number because I'm starting to think people are not doing their jobs and I've wasted too much of my life on phone calls and FCC filings that end up being a waste. Also, we should receive a refund on our accounts since we are not getting the services we are paying for.
