Extremely frustrating - give me answers

I have been trying for the past 3 months to speak to someone at the Bedfordview Branch to find out where the money in my account has gone to. I have been in the branch 3 times but the Consultants are so busy that my lunch hour is not long enough. The last time I was at the branch there was a gentleman apologising for the system that was so slow, but did actually nothing then disappeared came back half an hour later saw me still sitting there and said the systems are slow, disappeared again.
