Terrible service

I am having endless problems with NDA. First there is no communication and I have no clue what is going on. I had to call in to get my debit order arranged. And then the lady made a mistake and put through 2 debit orders,and they cannot cancel the one they put through by mistake. What is going on. And today I called my bank to reverse one payment which had been an error on NDA side,the bank has to wait 24 hours to reverse the payment. I need my money today. It's is NDA mistake and they cannot fix it. Service is very disappointing. At first you are so important afterwards there's is no communication and no response when I send emails. I need my money. I cannot wait till Monday to reverse from my bank.
