Very disappointed

I placed an order via the Woolworths application for food, the food delivery slot was between 16h00 to 17h00 and one hour later the food has not been delivered. There is no feedback on the app and we cannot get hold of anyone on the call centre number. This is poor service from Woolworths and leaving us athletes in a compromised situation having to divert to a different service provider for nutrition. Very very disappointed in your service Woolworths, I expected more.
