SD Next day guarantee 1pm help?
So I need a bit of help, I've got a prescription on the way to me with some serious medicines in it (all prescribed and authorized for transportation by RM before you say that) and they were sent off yesterday, last night I got the notification they'd be arriving today so waited in, when I checked the tracking at 1pm I found this so called up and they basically said they don't know where it is either or what's going on, no updates since 6pm yesterday!
I'm really confused and concerned, I needed this package today and yet again royal mail has failed me
Any advice or help here is very gratefully received and if anyone could tell me if there's a chance it might still show?
Thanks in advance
