The courier arrived 30 mins before the start time on the delivery slot I was assigned. Either s/he did not ring the door bell, or I had stepped outside (not expecting a delivery yet) and it has taken me several hours to rearrange the delivery on the dhl website as I kept getting error messages. It was not possible to telephone dhl to discuss this as it was not on the list of options available. This is not the first time dhl has caused problems. This was a delivery from John Lewis, and I've already contacted them to say that I will not order from them again as dhl's poor service reflects on them. I would give minus one stars if it were possible.
