Parcel in Yeep! Locker but no code from UPS

Parcel got delivered to a local Yeep locker on Wed, but I didn't get sent a pin or QR code to unlock. After attempting to use the useless UPS and Yeep apps to get details, gave up and phoned UPS customer service. After wading past their mandatory AI "helper", which took 10min, I managed to speak to a human operator who then put me on hold, eventually promising another team would email me a code within the new few hours. Which never happened.

I've now been round that loop 3x times over the last 3 days - each time calling UPS customer service, getting to a human operator, waiting on hold and being told they;re doing all they can and someone will email me a code. Absolutely shocking service from both UPS and Yeep... Yeep even worse as they provide no customer service at all, just refer everything back to the carrier.

Incredibly frustrating and a good reason to never use UPS + Yeep again, very concerned I will never get my parcel, which was a high value, one of a kind item!
