Debited in spite of services cancellation

I used sage (netcash) to collect debit orders and credit card payment from my clients. In March I closed my business and on the 20th March I emailed netcash to ask them to close the account I have with them. Anne-mart rep**** that the account would be closed (I have copies of all emails).<br> <br> This week all of a sudden my bank account was debited by them for R435.31! I emailed to find out why and apparently its because I didn't state that I needed to close the account properly... They have some internal sub accounts which I needed to apparently close individually (a bit like being billed by a service provided because you only cancelled the sms portion of your phone contract!).<br> <br> What made it even worse is that after my March email I was not charged for March, April or May. Suddenly June was billed for with July in July!<br> <br> I want an undertaking from sage that they will not debit my account again, I no longer authorise debits on my bank account by this greedy bunch of unsavoury characters.<br> <br> My account was for [URL Removed] (account number PHP001). STOP DEBITING ME! I DO NOT AUTHORISE IT!
