Stopped debit order and damaged goods

I was contacted by the Lewis store in Pretoria north regarding a payment missed. I advised I am changing my banking details and my payment date is changed I will come at the end of the month to pay cash in store for this month and from next month have a debit order set of my new bank account however today they took the money off the account with a debicheck one which I have never approved with my bank. I've never had a debicheck for my account but now they have a debicheck which was *****ently done. Ilthey took all the money that was left in my account and when I contacted the call center they said they will investigate but I must wait approximately 48 hours for them to investigate. This is unacceptable quick to take cash and do their own things but to replace the damaged lounge suite for months I am awaiting for this to be sorted from the time they delivered it the sales consultant says they waiting for replacement it's almost 1 year and he still has not replaced it.
