Dude, i Just posted about this in another thread:
During the iphone 5 times, I had to conference in Verizon and UPS at 9 pm at night to get them to demand to come and redeliver my phone because the delivery man just got tired at the end of his shift and marked the last few packaged "delay in delivery" and was gonna do them on his shift Monday. I raised hell and got the highest supervisor i could reach at Verizon conferenced in with UPS telling them she was gonna call their boss and report them etc. But i was a 20 year custom of Verizon so they bent over backwards.
Sometimes my UPS comes at 11pm, and sometimes they say too bad im tired im going home, delayed until Monday.
