No one violated HIPAA - these are telescammers who have autodialers to calls whole blocks of numbers. Sooner or later, they're bound to connect with someone who has diabetes or is pre-diabetic. Per whitepages.com, this number is " (305) 363-5285 is suspected spam Spam Level6/8 Spam reports last 90 days 7".
These people lie and say they have FREE diabetic equipment for you. Then they try to get you to contact your doctor and ask him/her for a prescription to be sent to them. They just want to bill your insurance some ridiculous amount for a meter that you can buy at Walgreen's for under $50. Don't answer.
If you're getting this call on your cellphone: Just click on the number so that no other numbers are listed. Then at the very bottom left of your phone click the the left bottom where it will look like 2 horizontal line inside what looks like a partial box facing down with the bottom line NOT there. You should have 4 options. One should say (Add to reject list) PRESS that option.Then hit okay. That number will no longer be able to call your cellphone.
