Stuck in customer service loop
So here's the story, skip the text wall to the bottom for my question.
I have a package set to be delivered tomorrow between 1-4pm. I will not be available to accept said delivery which requires a signature.
Upon checking the tracking, I'm presented with a message stating "Signature is required at delivery. Sign in advance for drop-off, or have us hold it for pickup" followed by a link labeled "Sign Digitally". So I obviously attempt to follow this link, get prompted for a pin, enter said pin sent to me. No option for signing digitally.
"Okay," I think and back out to the tracking page. Enter "change delivery options" to see if it's there, enter (new) pin; it's not there (it's the same link apparently). Go into the first "sign digitally" link again (pin, again), notice the "unavailable options", check there to see... no sign digitally there either. So clearly this option doesn't actually exist for this package in any form.
Fast forward a few minutes after discussing options with gf, decide to have the package held which was an option presented before. I select change delivery options and... "PIN entry attempts exceeded, the tracking number has been locked out." To be clear, the previous pin entries were copied and pasted directly, no incorrect attempts made. This appears to be a time based thing that triggers even on correct pin entry.
Clearly I have an issue now, call UPS and they direct me to call the seller to have delivery held. I call the seller (T-Mobile), and they inform me they cannot change anything and recommend using UPS My Choice. Okay, I have an account but I'm still stuck at this lockout. Call UPS, they can't do anything, tell me to call T-Mobile. Cue the loop. No one can change anything, I can reschedule for a fee, no problem, but only mon-fri according to UPS reps, and the weekend is the only availability I have before 7pm.
So at this point tomorrow will be a failed delivery. I assume UPS will reattempt delivery on Friday which will also be a failed delivery. Will the third attempt occur on Saturday? If so, great, but then why wouldn't I be able to pay to have it rescheduled on Saturday from the get-go? Anything I can do at this point or just wait for Saturday and hope for the best?
