I'm not even giving stars. I received an email to tell me that my parcel would be delivered that day. Nothing arrived. I received no call, text or email to explain why. When I tracked my parcel the next day, there was a line saying "We are having difficulty locating your property. Please contact us" I attempted to do so but my message was bounced back, saying that I should "try again later". When I placed the order I gave telephone numbers and my Eircode which, if entered into any gps, leads all other couriers directly to my door. I also put on the order form that my neighbour will take in a delivery if I am not at home. None of this mattered.
When I track my parcel now, apparently they have tried to deliver to me twice more...still no call, I've been at home all day, and until I search myself, there is nothing to indicate to me that anyone is attempting to deliver anything.
Disgraceful service. How companies can use this courier is beyond me.
