RIDICULOUS!!!!

I had such a horrible experience using the Woolworths Dash. I placed an order well within delivery time Saturday afternoon and had a customer service agent call me letting me know the driver is running a little late but my order is on the way. Little did I know!! The day ended with no order nor any other call advising that my order was rescheduled for whatever reason. Sunday morning and my order on the appeared appeared to have been delivered somewhere. I had to be the concerned user of course and call their call centre and was told some orders were cancelled. Now, how can orders be cancelled without notifying the person that placed the order? I was eventually told my order can either be dispatched again or process a refund. I was not going to wait for an order that might never arrive again and so I opted for a refund which I was told it would take 3 - 5 business days. Its been more than the so called 5 business days and I no one has called to let me know they are busy with the refund or anything, I have to keep checking. What has happened to the great service Woolworths is known for or am I delusional living in the past where Woolworths provided such amazing service. Absolutely ridiculous!!!!
