I can fully understand that a sp would like to be contacted from an unblocked number for their safety and security. However, I am uncomfortable calling from an unblocked number. My reasoning is as follows, what if the sp is not discreet and texts or calls back. This could lead to an uncomfortable situation. Maybe I am paranoid but how do others make initial contact when an email address is not provided and they insist on being called from an unblocked number. I look forward to any input on this subject.
