Mimecast is useless

We signed up with Mimecast due to spam protection on our clients end. Any of our clients that used Mimecast were blocking us. Firstly Mimecast sold us dreams with possible free admin console training etc. That all never happened despite multiple follow ups. I am the only admin and my cloud access keeps getting blocked. If I am blocked both my cloud acc and email client doesn't work (I cant send and receive mails). I am unable to help our internal staff because I do not have access. Last time I was told that I cant reset the password locally cause I am the admin. My password is always correct but I still get blocked. I dont know what to do. I contact them and the technician promises to call back and they don't. Right now the latest technician said that he cant find my company or my email account which means it has been wiped. I try to cancel the contract with them and they tell me I have to put in few months notice which then forces me to remain in this bizarre service I am receiving from them. I am a very unhappy client.
