poor service delivery

I've ordered an item yesterday to be delivered today and paid extra. Reason for the next day delivery is because I need the item for a client within 3 days. I checked the system to track my order, only to view that the order was cancelled and delivery is for 8 October. I've not been informed or received a notification. 2 weeks ago, a parcel was delivered whereby the delivery guy asked for fuel money. I ordered a chair, it broke and I retuned the item. They don't have what I was looking for and gave me a credit note: not a cash refund.
