Who called from 6072035692

Got this call on my cell phone.  It's very annoying and uses up my minutes since this is a prepaid cell phone.  Can't they be stopped?

What does this company do?

unwanted solicitation

Three calls, back-to-back, on my cell. No message left. Glad it is easy enough to block their number from calling me again.

Calling my cell phone several times a week.
