Depending on the value of local-pref - if they set it to "lower than for
other paths to that prefix", they won't use your path unless it is the
only remaining one.
Now which particular values a network uses for local-pref is a local
choice - the *default* value is 100, and "lower" means "worse", but
people are free to use 1000 for "customers" and "999" for "peers",
or anything else. Talk to your upstream, this is the only way to
figure out why they are still sending traffic to you and what you
should be doing differently.
Now, if your upstream is not able to answer that question, *change* the
upstream, because they are not worth the money you give them. There's
way too many idiots out there selling cheap bandwidth but not being able
to spell BGP, let alone diagnose and debug it.
