How can you block a restricted phone number on a cell phone

[dclark02]

My daughter is on the transplant list for a kidney in Colorado. She has to leave her cell phone on all the time so she can be contacted should a kidney become available. In the last few days she has received over 200 restricted number calls. How can she block that number. She is with Cricket and they told her it couldn't be done, but I find that hard to believe

Some cell phone provide black list service where you can enter those phone numbers if you have problem after this contact your network service provider.
