Who called from 4697578869

Just called my desk from 804-896-1075 and hung up after one ring. Immediately called my cell from 469-757-8869. This combination of events keeps happening with two different numbers being shown. Follows the same "having the first name right, but not the last" if I answer.

Got a call today at our office number in Canada.
Do not talk or ask for anything
This is the second time today

called me, no line connected and call dropped after several seconds

Same as everyone else, call from 4697578869, has vague information but accurate enough.

no msg left. they keep calling me from various numbers including this one. blacklisted. toronto
