ACCOUNT PAID IN FULL, STILL WAITING FOR A SETTLEMENT LETTER!!!!

Hi please note that I'm still waiting for the settlement letter, I've mailed your customer service and legal departments many times providing them all the documents they asked for, inlcuding a paid up letter from the collection company, whom have been paid in full. Every time i follow up with Vodacom, I've been told the same thing over and over that the matter has been escalated to your subscriber collection. Im sick and tired of Vodacom giving me the run around and i will never again deal with them, i just need you to update and close this account on your side because its affecting my credit profile.
