Who called from 2813062278

Hello Name, I am calling from a collection agency on a Sprint wireless dept of 758$

Incredibly rude debt collectors. I haven't had any open account at sprint for over 6 months and I get the "ring ring hangup" at least twice a day. Very difficult to get in touch with a representative. I resolved the fallacious charges with sprint and now unable to reach these bozos to tell them.
