paid up letter not sent

I have been in contact with a guy called Adeeb regarding my account. I was told to pay R619.99 to get this account closed and my name cleared from ITC which I did. I made this payment on the 22nd of June. On the 23rd I called and spoke to Penelope from subscriber collections who told me my account has been deactivated and needed to call accounts for the paid up letter. I called accounts on the same day and spoke to Lesego who told me my account has been cancelled on the 31st of Mar and referred me back to subscriber for the letter. I called subscriber and spoke to Philemon who told me to call on the 24th as my payment hadn't cleared. On the 24th I called and spoke to Eshwin who promised that I will get the letter in 48hrs. I waited as usual. On the 29th I called and I spoke to Nompilo who told me Eshwin was supposed to log a service request which he did not. She transferred me to Lethan who told me I will receive it in 48hrs. I waited. Today is the 2nd of July and I still haven't received the letter. I called subscriber and I spoke to Khanyisile who gave me attitude telling me that there's nothing she can do except escalate this request. I'm fed up and want this letter!!!
