No assistance almost a month

I’m really disappointed regarding the service I am receiving. I did go to the branch to inquire regarding account closure 2 times different branches and also did the on line enquiry regarding the account closure because of the failed debit orders and I did mention that I don’t afford the bank charges that are occurring when the debit order bounced due to insufficient funds and another constant advised that they can look at my account maybe I can change the type of account I have but nothing has been done the incident that i have is for the 18 of May and obviously the bank did receive my request for debit order switch but they did not see a need for them to assist me and now I’m owing the missed debit orders charges which would have been avoided. When going to the branch you stand for long hence I was glad I received a call but now I’m really disappointed with this service such a big bank and I have been the client for a long time even the last time I had to migrate to another bank because of this and I am doing the same even now.
