I got an email address associated with TMCC when I attended back in 2011. I was told then it was free and I could keep it. Yesterday without notice, they disabled it. I have used that email for 8 years and have important info on that account. When I asked if I could transfer it over to my Google account, they told me only if I applied and was accepted as a student at TMCC again. I am done with school and I dont need to go back. Now I'm unable to contact anyone to get this resolved. All lines of communication have fallen silent!
