Bad management!

Having ordered an in-stock article in February, the latest date of delivery was indicated as beginning of March. Phoning them today, I was informed that the item was out-of-stock and that a voucher tot the total amount has been created on my behalf. They supposedly sent me an email to this regard around the time of expected delivery. I didn't ask for a voucher, and didn't receive any email. The agent didn't even apologise for the mess-up.
