Very poor service for order deliveries

I purchased a washing machine and hairdryer online and paid my R250 delivery fee on 20th November. 22nd November I received delivery of my washing machine, no hair dryer although the invoice states the washing machine had to be delivered with another invoice (for the hairdryer). I phoned 6 times to the store that did the delivery (Silver Lakes), every time they will follow up, or another excuse given. Its no 10 days after my order placement, I still have no hairdryer. Absolutely shocking service.
