Who called from 5513229000

I received a call from this number. Anyone knows who this is?

It is some online pharmacy.  I have gotten 3 calls today from them from various different numbers.

I just received my second call from this number in the last hour. Both times they were hang ups

These people keep calling me at all hours of the day! I answered once and it was some college loan thing, and I asked to be placed on their do not call list. The lady SWORE at me and then hung up. Sure enough, 10 minutes later they called again!!!! How do I get them to STOP calling??
