Private client service poor

I am a private client, paying an extra fee to receive personalised service. In the last year I have at least phoned my personal banker 6-10 times for assistance, and not ONCE did the person pick up the first time, nor did I receive a call shortly thereafter... again today, my personal banker was not available, and when transferred to another PB, I was cutt off from call before any answer... poor service. I definitely do not feel like an appreciated client.
