Shocking Service and communication.

I placed an order on 29 May. Delivery date 12 June as items had to be shipped. Then delivery date moved to 22 June, no explanation. An item got cancelled. Delivery moved to 29 June no explanation again. Call the call center... the message tells you they open from 10.00am - 6.00pm on a Saturday by no answer. I am not impressed, no communication, shocking service, I am just wondering what else will be cancelled during the month it is taking them to deliver. Not even an apology for the bad service!!! They don't want to hear from you either as contact details are not easily available!!!!
