XDP were to deliver items on behalf of B&Q to my home address. Immediately I received information that XDP had the items in your systems I informed you of two dates when I would not be available. I repeated the email and yet you just delivered it anyway. As a result, I had to postpone another important appointment. To add insult to injury your customer-diservice staff gave a lame apology and stated that changes to delivery details cannot be guaranteed. In other words, the customer comes last. No wonder your review ratings are abysmally low.
