Incompetence at Barrett Legal

After Numerous attempts and emails, I negotiated with FNB a settlement letter and paid up the outstanding amount requested, yet after talking to Barrett Legal and e mailing them the proof of payment and the FNB settlement letter, I am still on the ITC and still getting SMS's everyday. HOW DO YOU NET GET THE MESSAGE IT HAS BEEN PAID TAKE ME OFF ITC! Please would you read your mails and finalize this issue. For GOODNESS SAKE.
