tcp/ip question

They say that tcp/ip (as opposed to udp/ip) is reliable and gaurrantees
packet delivery to destination. But if some rounter along the way is too
busy it drops packets and that is why sometimes we see a page not being
loaded or a file being downloaded just stops in the middle and we end up
retrying the action. So how can tcp claim that it *guarrantees* packets are
delivered safely?

The TCP protocol requests to repeat transmission of any missing package.
The effect is a slow-down, but the integrity of the data is not compromised.
