My husband keeps getting calls from this number. They always say they're the supplier for his diabetic supplies for his insurance company. Yet they do not know the name of his insurance company. They appear to be asian and so long as they are asking questions they stay on the line. I gave them the 20 questions last time they called and they hung up on me. They just called again and as soon as I told them to put my husband on the "DO NOT CALL" list they hung up on me. I tried calling them back and got the following message "The number you have dialed is not in service. Please check the number and try again. Goodbye." I wish I knew how to block their calls but I will just continue to waste their time asking them questions each time they call until they decide to hang up on me again. LOL
