calls daily, , leaves no message

This is from a company called CCS Medical.  They help people get their diabetes supplies at no cost.

Answered phone. Caller ID was 727-531-9161 . No response to "hello". Remained on line for 15 sec. Still no response.
IF this is a spam call - I am registered on a DO NOT CALL list with State Atty General.
They shoulod be aware that I am reporting them - and that the FINES for such calkls result ifor EACH INSTANCE of said calling.
Everyone else should likewise notify their individual State Atty General about this breach of spam calling..

This CCS Medical calls me 2 to 3 times daily, even though I DO NOT want them to, I DO NOT use their services and I have repeatedly told them, "DO NOT CALL ME EVER AGAIN!!!!"

This is CCS Medical Supply. They send me my glucometer test strips. They used to be good, but lately if I dont mail back the form the day I receive it, they go nuts calling to ask same ?'s from mail in form. Even when I talk to one of them abt my order I may get called a couple more times by different office ppl. Iv told them its annoying but duznt seem to matter.. Going to change suppliers.
