I requested this call
This call to me was a legitimate call, though I didn't have my phone with me when they called back. Left a message like: "Press three. I didn't hear anything. If you're ready to speak to an advisor press one to reschedule this call for another time press two. If you change your mind to cancel the call press three. I still didn't hear anything. We'll try calling again in 10 to 15 minutes. Goodbye."
This is the support number.
