Collebhu bad service

I have been calling a debt collection company called COLLEBHU. This has to be the most pathetic and most unprofessional company I have ever dealt with. Criselda and Zinzi who happen to work for this company are the most useless and *********** people on earth. I have been requesting a paid up letter for an account I had for the past few weeks to no avail. I have been told tomorrow, tomorrow a million times and now I do not even know what to do anymore. I hope God deals with you decisively some day Miss Zinzi and Miss Criselda.
