Sent two parcels to a customer on 3 December 2019. Customer phoned them to give them an updated address, they only updated one parcel which they delivered. The other one they decided to return to me. It turns out they had my old address, but they refused to send the parcel to the new address. It has now got lost, and no-one has replied to my complaints. Call centre is impossible; long wait, and the staff can hardly speak English. When they do, they tell you contradictory stories. Finally got through to a manager who only identified himself as 'Q' !! In short, they refused to deliver my parcel to the correct address, yet with a determination that might be applauded under different circumstances, returned it to someone random despite being told repeatedly that I don't live at that address. Absolute shower, won't be using them again.
