Fastway not contactable

Be wary of using Fastway. There doesn't seem to be any way to contact them? I received a confirmation that Fastway says my online order was delivered but it was not. I have been home all day. There are no options on call centre to actually speak to an agent. It's just an automated system taking you in circles. They suggest using their online query system which just comes up with an error message and they mention online the other option is to contact them by Whats App. It's been approx 7 hours and they haven't responded yet.
