unable to log into account

I am hugely disappointed with the service i received from show-max, I tried out the 14 day free trial which I knew i would be billed for if i did not cancel before the 14 days ended, however was I not suppose to get an email notifying me about my free trial ending soon? also i feel as tough i was forced to have a subscription as i was automatically now a member after i was billed, when i try to log in with the details i used it won't allow me it keeps saying" invalid email address or password'' same email address they used to inform me about the subscription is suddenly invalid.. I am highly aggravated by this and it should be dealt with immediatly, i just want the subscription to be cancelled as It states i will be billed again on the 14th of October for a service i can't even use because i can't log in
