TERRIBLE Customer Service

The customer service has been awful. I have had an issue with my account for 10 months now. I was originally told it would take 30-45 days to have it resolved and here I am 10 months later no further forward. I have phoned the various contact numbers given on NUMEROUS occasions and am usually on hold for 20-30 minutes before being told this is not their department and I need to phone someone else or get transferred elsewhere. I was once transferred back and forward between the same departments 4 times in the same call. I always have to initiate the calls; they have never contacted me. I got the manager of my local branch involved and he has gotten nowhere either. I also contacted my "private customer" consultant who told me that I should maybe just open an account in another ban**** How do you expect your customers to have faith in your business when your customer service is so appalling?
