Woolworths and their tired time slot excuse

Some days ago I complained about Woolworth's bad service and now I'm here to complain about the exact same thing again. I tried to order online the other day but it was impossible. I couldn't add groceries to my cart no matter how I tried. After complaining, I received a call from a polite guy who told me that the time slot for my area was full and that I should try the next day, I did that and got the same result. I gave it a rest. Thought Woolworths would evolve with the lockdown, become a little more effective however nothing has changed which to me means they can't deliver where I am. Then take the place off your list but put a pull down list of areas you service so one can see right from the beginning so you don't have to go through wasting customer's time. Horrific service.
