Unprofessional clients service

These debt collectors are unreliable and the call center agents are very rude. After making a settlement payment on my defaulted account. I sent emails and called to get a paid up letter and my credit information be updated but even today. I haven’t received it, I only received a reply email from a Hazel Mthembu saying “Be patient we will send you” no apologies for late reply or Reasons why the paid up letter and the info is not updated on itc.
