Delivery has not arrived

I made use of the Woolies Dash app yesterday, 03rd of Feb for delivery between 17h00 and 18h00. At 17h50 I received an sms notifying me that my delivery was running late and that it would be with me shortly. At 18h24 there was an update on the APP saying that the delivery was completed and it wanted me to rate the service. I immediately tried to send a message on the APP advising of the situation, to which I still have not received a response. I have tried to contact the contact centre twice yesterday and again twice today and apart from holding on for more than 30 minutes a time, the call keeps disconnecting without assistance at all. I have sent another message on the app and an email to *** with no responses to these as well.

Still no idea where my delivery is and I'm not being assisted by anyone, I have run out of ways to contact Woolies and I am extremely frustrated at this point.
