False advertising of stock availibility and unacceptable delays

They advertise items as being in stock then say they are ordering from an overseas supplier, after which I am sent delay after delay after delay. I needed the item urgently so long ago and till today, 2 months later, they cannot provide me with an actual date I can expect to receive the item in my hands. They don't even give reasons, just send out these generic emails and expect you to wait for them to actually take the effort to fulfil your order
