Bad experience

I'd like to share a very disappointing experience with one of your collection agents by the name of Lesego Mataboge from the Deceased Estate, its been almost 2 hours & we have requested for a letter for what amount is due to bring the account up to date, not the settlement amount Including this month but no answer by this lady who had so much to say to my mother, my mom's company is looking for a letter stating how much is needed to bring the settlement up to date but she has failed to assist us with this simple request...

Could someone more senior get back to my mother in regards to this matter her number is
