Your service sucks

HELLO, ITS ME AGAIN. Yesterday I called to have my contract cancelled, and asked for confirmation letter to which your consultants said I will receive "SHORTLY" after the call. This morning you deducted your cancellation fee from my Bank as arranged, but now you are saying I will only received the cancellation letter in 20 working day (as per Themba whom I spoke with this morning). What I need from you is this1. Uninstall/deactivate your device ASAP as I have paid the cancellation fee....2) Send me the cancellation letter. I am tired of calling your Call Centre and getting contradictory information.....
