Bad customer service

The level of unprofessionalism this company shows is disgusting ,a week ago I called in to ask for a Recording when I joined the insurance and I was told they were gonna revert back to me within 3 days and they failed to do that ,I wrote last week no response I am writing again and I won’t stop until they revert Back to me and take my matter seriously.i will write in all the social platforms if I have to until they give me the treatment I deserve . I want the recording that states I have to pay access for my phone to be repaired or get a new one .
