Paid Up Letter

I was offered a 20% discount on my Edgars account by Norman Bissett & Associates last year and the outstanding amount was therefore paid in full and I requested to get a paid up letter from Edgars West street in Durban and they advised me to contact Norman Bissett & Associates whom offered me the discount. I then called Norman Bissett & Associates to inform that the amount agreed on has been paid and to provide me with a paid-up later, the lady that I spoke to advised me that it will take a few days for the payment to reflect and once it has, they will then send me a paid up letter. Months passed and no letter was received
