Account Settlement

I'll never again be in business with homechoice, and this is not happening for the first time I have settled my account in October but they keep on debiting my account, and I did call them with my airtime asking them to cancel the debit order because am done paying, the lady that I spoke to told me that it's sorted it will never happen again, but Guess what it went on again this January that is soo inconvenient to me and the unnecessary bank charges for debit order.
