  1. 1

    Determine the number that you wish to block. If it's a harassing call, write down the number that appears on your caller ID. If the number is coming from an automated system, you may need to call the owner of the institution responsible for the calls, and have it corrected.

  2. 2

    Call your cellular provider's customer service department. This phone number can be found on the provider's website.

  3. 3

    Avoid the automated system by continually pressing zero. With a representative on the phone, identify yourself, your account, your phone number and provide any password information if instructed. Explain your request to the representative, emphasising the speed with which you need your request filled. Offer your phone number and the phone number you wish to block on your account. Obtain the representative's name, title and extension.

  4. 4

    Contact your cellular provider's technical support department immediately after speaking with the customer service representative. This number can also be found on the provider's website. While a customer service representative may have already handled the problem, technical support can verify its completion. Provide the customer service representative's pertinent information to clarify and expedite the tech support's search. Ask if your request has been handled, technically-speaking. Obtain the tech support representative's name, title and extension.

  5. 5

    Wait 24 to 48 hours. If the phone calls continue from the blocked number, contact customer service. Immediately ask to speak with a supervisor or manager. Explain to the superior your unresolved issue, provide the names and extensions of the previous representatives, and wait on the line until the number is successfully blocked. Again, ask to be transferred to technical support to verify the correction. If the problem continues, repeat until it is resolved.

Tips and warnings

  • Be courteous when speaking with representatives of a company. They will be more likely to help you if you are calm, patient and kind.
