user: waited in all day for my parcel to get this email. Next day delivery at its best I see. Absolutely fuming, what a waste of a day, I suppose I've got to wait in all day tomorrow now!
agent: I'm so sorry to hear your delivery was not made today! Keep us posted if it does not arrive tomorrow.
user: I'd much rather have an explanation as to how it failed?
agent: Happy to help, Xan! We don't have access to your account via Twitter. Please contact us by phone or chat and we'll be happy to research this closer for you: Please keep us posted!
user: Somebody emailed me, they marked it as high priority to be delivered today, it's now saying it's been delivered, I rang my mum, she said nobody has come to her door at all. I've now sent another email. More fuming than yesterday now!
agent: Sorry to hear that. Can I ask if you've checked with your neighbours or any safe locations around the property?
user: Yes we've checked, they have said that the driver scanned the parcel and sometimes it comes up delivered when it hasn't. My mum is going out at 3 they've promised it will be there. They will investigate it as it should have been delivered yesterday.
agent: Thank you for that information! Please keep us posted on the outcome!
