Poor service offline

I'm extremely disappointed as I had to take time off work and the only time I can get this week I get to your branch and I'm told they are offline I want to do a dispute on my account and I was told to sit for 5mins but it's been more then that no one is getting back to me. I asked if there's another way to dispute telephonically and I'm told no I asked if I could go to another branch was told they are offline as well without even phoning to find out if they are.

I'm not happy at all cause it's a different branch that is offline for the second time in a space of 2 months. How can that be I don't have time for this I'm considering closing my account.
