Does anyone know who this is?

This number calls multiple times a day, always speaking with some kind of accent that I can barely understand. They call stating that it's time to upgrade my diabetic testing supplies and they seem to know my insurance provider. When I asked how they got this information they said it was in some kind of data base related to the company. When I asked them to spell the company name (in the hopes that I could finally figure out what they were saying) all I got was "b-e-t-t-e-r-o-f-f-something-d-a-y. When I explain to them that I am on the do-not-call list they argue with me and tell me that I'm not. I've asked numerous times that they stop calling this number, but the calls persist...every day.

I actually caught them last night in the "right" mood and after having told them nicely several times to quit in the past, I let loose and the guy accused me of phone harassment.  I demanded he take me off their list and he said they did....until I got 2 more calls today.  I answered one of them and he hung it up.  I just need to find who it is so I can report them

These people are calling all times of the night and identifying themselves as The American Diabetic Association. I have asked him repeatedly to stop calling here and I'm getting tired of this. My grandmother is elderly and has dementia and if she happens to answer the phone anything could happen!

Multiple calls all hours from 3368330898. Most times they hang up after I same my name and ask how I can help and say that twice them click. Within the hour I get 2-3 more hamg ups from different numbers then a call from them w a love person. I have asked multiple times to be removed and its non stop. Sundays, very early, very late, holidays. I don't want to change my number, but it's beyond annoying now! What can we do????
