Residential Customer

My package is now 3 days late. They promised me delivery and claimed that because I was a residential customer it trips up their system. They do not return calls, make false promises and I would never use them again! I told them I was willing to forgive being late but they absolutely needed to deliver on the third day late! I can deal with one day late, three days is inexcusable and the communication is horrible! Beware don't walk away - run away!
