I had to transfer more money from savings to the main account so I went called into my manual banking service. There I had to identify myself of course using the numeric tones. Nearly every time I tried entering my personal security number or the password that damned keyboard issued double-taps (sent the same number twice). This ended up in that I locked my phone service account. This was a serious bug and it was consistent. It sent the same number twice intermittently and irritated the hell out of me.
