I was there with my appointment on February 26, and the guard recommended to another man that they try on the network to make an appointment on the 15th or end of the month, which is when they take the appointments for the following groups of the month.
I had to call daily and I also made an account on mexitel.com and I put a password that was strong for example (Flower%_01) and that's how it was able to let me in to see what appointments and days they had available. I understand your frustration. If that doesn't work I would maybe try to do another account with a different email. Good luck to you .
