Person2:Hello , yes , I'm a stock investor and I'm looking at opening a new account with you . Perhaps your new compound savings one ? I already have a Current Account with you .
Person1: That's no trouble , Sir .
Person2:I'm mostly interested in the personalized services you offer , with stock market news , etc . It sounds just perfect for me , as I'm too busy to be constantly at the computer checking the performance .
Person1: Yes , that's just one of the services we offer in our Personal Financing Program .
Person2:What I need to know is how I can keep track of what's going on . I mean , some days I buy and sell quite a lot . Some days , there's no activity at all .
Person1: For every transaction you make , a statement will be drawn up and can be posted to you or sent via e-mail , or if you want to be double sure we can do both .
Person2:That's just what I need , sometimes I'm pretty forgetful .
