Airbnb provided no help when needed

I tried desperately & for a long time to contact airbnb. My host does not respond to my emails and airbnb does not respond to my emails. What I get from airbnb ( is “Email not received”.  I have to move in host place on 27 October and don’t know for sure if I have an accommodation there. I don’t have a phone and calling their number is another nightmare. What kind of business is airbnb running without online access to customer service?  It is really become shonky, while they talk about trust & community.  Shame on you, Airbnb.
