Poor service from Nikiwe and the entire Unifi team

This is by far the unprofessional service ever received from unifi. Who gave you guys a permission to call me on my work phone. When have I ever ignored your calls or not made a payment. There is an outstanding payment of 1028 of which an arrangement was made and my account t hets debited on a monthly basis and you have the audacity to call my job and look for me. Did you loose my number??? Did you loose my email address. Was there a month where a debit did not go through. Stop with your nonsense and stick to what we agreed on. This is bull****
