Stadio poor service

My child is doing the BED Foundation phase, she is first year 2nd semester, she has already registered and paid registration money but has not received anything yet, her classes started today but her ECI profile is not yet loaded and she has no list for books, their first Zoom is Saturday but she still has no link or anything. I have called every possible number but no one answers, ***, and ***, there is a machine answering but if it has to put you through or if you wait for someone to answer you are cut off. I'm very disappointed in the service, or would I say I get no service, no emails are answered and I get no feedback. Can someone please help me or give me the head of Stadio's nr.
