I booked a locker and went to deposit my parcel

I booked a locker and went to deposit my parcel. At first it did not scan the QR code i then went on and type in the code that was sent to me. The locker did not open. After several attempts it shared that my code does not work anymore. I phone the help line and the first thing the Operator asked me was if I made a video? (*****)i then locker a query and the response was that they have checked the lockers and it is working fine. I had to book another locker to send my parcel. No refund from these ******
