Refusal to assist with Query

I have called three times, I am trying to port my number and each agent gave me a different reason why the porting had failed. I requested to get an explanation for the failure to port in writing (via. Email) and she refused to assist with my request, I then requested to speak with her manager and this she also refused instead she put me on hold and after 10 minutes, she said she would get a manager and she put me on hold again. A few minutes after this, she hung up on me<br> <br>
