please cancel my account

This is the 3rd time in 12 months where I have had issues with clientele legal debiting my account on incorrect dates! My agreement is to have my account debited on the 25th, you debited it on the 22, I have two accounts with you. This meant that the bank charged be unpaid debit orders twice at R138 each! I end up paying the same amount in banks charges then I do in the policies!!! I want both the accounts cancelled with immediate effect!
