Useless and not fit for purpose. However, they have a very good, if inaccurate, tracking system. Total inability/unwillingness to respond to emails. I understand that delivery can go wrong but when it does it is incumbent on the courier company to put it right as soon as possible and KEEP THE CUSTOMER INFORMED. XDP fail miserably in this regard. I am still waiting for a response from their Stockbridge depot despite having sent 2 emails. In addition during a call I made to their 7p/minute telephone number, I was assured that the driver would be contacted and would call me directly with a delivery time. So far NO RESPONSE. My overall attitude to this shower is DO NOT USE. There should be a no star option for this outfit. ......and still I wait!
