Have received calls over the last several days from various numbers, but the call is conducted in the same manner. They ask for me, I ask who is calling, they only give their first name - will not say where they are from or what it is about. They continue to ask for personal information. Since I am not familiar with this person, I simply say they have the wrong number and to stop calling. I do not know what this is about, but it is beginning to become bothersome and concerning. The other numbers involved are : XXXX ; XXXX ; XXXX ; XXXX. Again, I believe it is the same organization just using different numbers.
