as per UPS.COM--
Your driver will make a second attempt on the next business day, and a third attempt on the following business day, if necessary.
72 - it's no wonder u have so many complaints against u - u need to make consecutiveattempts---oooops, my font key is stuck again.
That the problem a package could get put in the wrong truck thus it would be sheeted missed so there would be not attept that day. In this case the call tag Probably wasn't turn back in and or the clerk never reprinted it or put it out the next day. Weather might have also effected why three consecutive attempts where not made. Like I said before each package should be sheets each day that doesn't mean there was an attempt to deliver.
Well if people are complain about the service that I provided I haven't heard anything about it.
