Poor service delivery

Please stop advertising that you deliver in 60 mins.

Very bad service. They only have excuses and there's no support from the call centre. I was scheduled for delivery between 12pm to 1pm yesterday but only received my parcels at 3:30pm. I got a notification that my groceries was delivered at 2:11pm but I did not receive anything at that time. I placed another order yesterday prior to the bad experience as mention above and it was scheduled to come today between 12pm to 1pm. I then get a call telling me that groceries is not going to be delivered on time because the driver is not available right now due to an emergency and if I can go to him and collect my goods. What non sense is this and what poor customer service. This is outrageous.
