Same here. Symptom was i'd call, get one ring, then fast busy, then very fast busy. I tried this on more than one 800 number with same results.
I called support (866 number and it went through correctly) and they made changes, had me unplug 20 secs.
Redialing the 800 number I was trying to call (my broker)....first time I got just fast busy.
2nd time the call went through...but to the wrong bank (Chase, which is not at all affiliated with my broker).
3rd time...call went again to Chase customer service.
4th time, and subsequent times....it went to my broker correctly.
I was using REDIAL on my phone so the calls that went to Chase in error were not misdialed by me.--
