Paid Up Letter

This LGR Group they buy accounts and calls you, email you, sending SMSs, when you settle the account or accounts, they don't send you a Paid-up letter when you email them, they ignore your emails. I've sent several emails requesting my Paid-up letter spoke to the lady by the name of Nonhlanhla whom she promised i will get it by the end of a business day, but it never happened. spoke again to a lady by the name name of Elsie Sithole she asked i sent her POPs on her email address *** after that she never responded, i also sent emails requesting my paid-up letter to ***, ***. also, to Lerato Molahloa on email ***. all they don't bother to respond. Their account is paid in full but both parties they ignore you when you want a paid-up letter. i have all the correspondence on emails with them saying i want that paid up letter.
