Adumo Premium Imali card, are they legit?

I am new to Adumo and on register a card received I could not even read their terms and conditions I need to acknowledge. every single so called terms and conditions gives you an error page. then on trying to call the contact number the number is just dropped. no answer. How can I even consider to register something when its starts out like this. very scary!!! who makes someone sign T&C's that are not even availbable.
