I have made a mistake and I am sorry for the bad review that I posted last night. I persevered trying to return my order and although I was becoming very frustrated because it would not work once I had cracked it I realized that it was not really that difficult. When you enter your order reference you have to put a dash between the second and third set of numbers, only then does it work.I was then able to proceed to obtain a QR code,take my parcel to Asda where I was shown how to scan my code to obtain a sticky label to attach to my parcel. Success-job demand I suppose practise will make perfect so maybe I will chance ordering from YOURS in the future.
