May I help you ?   I have a problem .   What ’ s the problem ?   Someone else is making charges on my debit card .   I need to see a statement for your debit card .   I have it right here .   Can you show me which charges you ’ re referring to ?   The last four charges .   We will need to do an investigation on this .   How long will that take ?   We ’ ll have to freeze payment on those charges until the investigation is finished .   I really appreciate your help .
