No technical support at all on weekends

The company had installed a camera system in my complex. I am in charge of the security portfolio but the have not once made contact with me. We have hade an incident on a Friday afternoon and I was going to review the footage the next day. Unfortunately for me I did not have a password or user name. So I cannot access the footage. So I have a system but cannot do anything. This is because Duma tactical support does not exist on weekends. There were no specifications give to indicate how long the footage will be there for review and the system might overite the existing footage. I am absolutely unsatisfied with there service and this is only there first month.
