Can people track me with a cellphone call?

awhile ago i had a phone call from a number i don't know, i answered it cause i thought it would be one of my friends, but then it wasn't one of my friends, then she asked me how old am i, she asked my location, she asked me where i buy load for my sim, she asked me if i know that there's a 10% discount on load, if i buy load in SM (name of malls here in the philippines). then she told me that she called just to say that. im scared the **** out of me, im scared that they might be robbers or murderers or kidnappers, is it possible for them to track me? the length of the cellphone call was 1 minute 34 seconds :-? :| please help :(
