When the response team calls, they will always inquire whether you are available to talk. If the time is not appropriate you can arrange another call. If you are unable to answer the call, they will leave a message and attempt to call at a different time. After the fourth attempt you will receive a message that they have been unable to reach you and will make no further attempts. If you still want to be contacted, you are always welcome to write to email@example.com or call at 88877700.
