Bank keeps messing up with my accounts!

I opened a cheque account in June. Absa then informed me that I would have to change all my debit orders myself,other banks do it for you when you change to them but I started the process and a lot of calls later it was done. Come the time for my debit orders to start going off, I got a lot of them that bounced back as they still went off my savings account. Granted, the ones not from ABSA are not Absa's fault. But one of the payments that bounced back is the payment for my Vehicle finance. Took another 1 hour phone call to fix and get informed that I would have to email the credit dept so that they do not blacklist me even though the bank made the fault. I then had a payment go into my savings account, and ABSA deducted my vehicle finance for a second time from my savings account again. I went into the Branch where I had to fight with a person over the phone to get the payment reversed. This month my vehicle payment was supposed to go off on the 31st, it didn't. Phoned this morning and was told I was supposed to make a cash payment, my debit order was cancelled. This is not acceptable, I am thinking of moving banks completely!
