I've been purchasing FedEx shipping labels using buy shipping on Amazon.,

These shipping labels have 2 tracking bar codes on them., Fed Ex tracking and USPS tracking.

I drop off these packages at FedEx location.

Lately I've had few packages in which tracking does not show update on Amazon, and then

when I check the tracking on FedEx website, it is showing FedEx in possession of the package,

and Package has transferred to USPS to continue delivery.

I check the tracking on USPS website, it shows package was processed at USPS facility, and there will be delay.

And there has been no update on these packages for 2 weeks.

These are expensive items., and buyers are causing problems.

Anyone else having issue with these type of labels from FedEx?

I have stopped shipping with FedEx, until I can find out what causing this.
