ABSA life *****s my money

I have a funeral policy with absa and have never missed a premium. Recently on 24 August i made an enquiry and found that my polict had lapsed for no reason and so required i made a payment of 3400. When i asked which premiums were missed i was told none and so it will be sent for investigation and that i shud send 3 mintgs bank statement to fast track the process. Which i did. On the 25th debit order date 3400 was debited from.my account without my authorisation and reinstated the policy. I have contacted absa life 4 times and they jeep.on promising to assist swiftly and return to me but nothing has been done. I have other commitments withbthat money and absa does not take me serious enough to assist. Sonim warning all.people to be careful with such banks as they *****.peoples moneys and do not care for their customers. Im angry and do not know what to do anymore.
