This has been posted before... if you use multiple services and you give real general contact information instead of using only a designated number for gaming this will happen. Your name and number can be quickly disseminated depending on the service used and who is in the tech or IT and even CSD department. There is a large underground market for player lists in CR... SBR may not be the culprit and this information can hit the distribution network based on many factors which may not be because of SBR. Use a DESIGNATED number for gaming contact that goes directly to voicemail and check if
you are looking to deposit or just delete the messages regularly if not, simple right... annoying calls goaway.
PS if you had a BI account then everyone has your contact info...
