Account cancellation quiry

i have requested a premature cancellation fee to cancel my contract they sent me a quotation and i paid it on the 4th March 2016 now when i tried to get a paid up letter i have been transferred from the cancellation dept to the credits dept back to the cancellation because they say the line is still active then the cancellation dept told me it shows active because its now prepaid then they transferred me to the accounts dept to request the letter there then they transferred me back to the cancellation dept because they said they cant help me then the cancellation dept transferred me to a new 3D or something dept because they say its active there then this dept told me that they got to get hold of the cancellation dept because they got to do the cancellation, which took me half of the day find out and i'm still waiting on them to get back to me after sending almost 2 hours on the phone with them so i am really ppp....ed off at vodacom for not being able to do their damn job properly.
