PAID UP LETTER

Telkom had me listed at Transunion, which I obviously was not aware of. When I found this out I immediately called them and had the account(mobile account) settled so much so that I am now in credit with Telkom. I have requested a paid up letter from them on the 05 February 2018, I was told that I will get this within 72 hours. I called them(incidentally, I waited for an hour before anyone answered) when the 72 hours was up and was told that it would be 72 working hours. I waited out the 72 hours working hours and I had to call again, whereby I received an email. I have since sent 4 emails to "Nospiho Desiree Mkhwa**** (N)" ********** cc: "Sinenhlanhla Thabethe (S)" ********** stating that the "email" will not suffice, as Transunion requested an official Telkom letter. I even threatened to go th the National Credit Regulator and to date, being the 18 April 2018, I have had no response and certainly no letter. This is most frustrating:-(
