Cancellation of contract

After my last 2 complaints of the same query, still, I heard NOTHING from Vodacom's Legal Department. Actually, I received a letter of demand to pay my account! I do not now how to get it in their heads that I CANCELLED the account for how many times now, the first time more than 2 years ago!!!! Their account system is BAD, more than BAD!!! If I could mark complaint to worse, to bad, to very bad, I would have done that! How bad can they get? Let us have a look!!!!
