Hello,
I am sorry your are having difficulties. I hope this information helps.
You are able to log in to the Cox Webstie and set up phone tools. Phone tools will allow you to look at your call history. As well phone tools does also offer some additional features. However, phone tools does not give you the option of blocking phone numbers.
Cox does offer a feature called Selective Call Rejection. This feature keeps your from getting unwanted calls. This feature allows you to program your phone to reject calls from any number you place in the rejection list. This feature will allow you to hear the phone numbers that are on your list.
I hope this information has helped you. Please do not hesitate to ask if you have any further questions.
Sharon
