Poor Customer Service. Once Payment has been made, they cut all communication with their clients.

I was called by Michelle about the offer to settle my Finchoice Account & said I will receive my Paid Up Letter after 2 Weeks. Now its been a month since I settled the account and no Paid Up Letter was sent to me. She no longer responds to my emails or Whattsup.

What exactly must I do to receive my Paid Up Letter?
