UPS shipping issues with new iphone

My new iPhone was shipped two days ago with UPS. On the second attempt on Oct 9th they said it would arrive 10am to 1pm, it did not come in that window are we waited around a long time and we had to leave the house and missed it at 5pm. On the third attempt they gave us incorrect shipping info saying it was going to show up Monday Oct 12th. UPS did not notify us at all and they came yesterday October 10th. We were not home because we were told they would try one more time Monday and we missed the last attempt. It is currently being held at the UPS store but we can’t schedule a pick up because of Xfinity. We need to be able to pick up the phone so it doesn’t get sent back and we loose the promotion/upgrade. 

We are very frustrated. We understand that we have to sign for the phone but how are we expected to sit around all day while we have work and kid activities. UPS has provided windows and dates that they did not follow twice, therefore we missed the deliveries. We know you can’t control UPS and their shipping info being incorrect but there is no flexibility that we can change delivery or pick up because of things on your end.
