Disrespect for a Client

CCD Couriers representative called at 07:28 today. Without introducing herself, she says "Can I speak to Trevor" What disrespect for a customer. One wonders what training these people receive #SupportLocal ? Accepted business practice is, where you have not been introduced to a client personally, the client should be addressed on the clients' Surname. It just shows that there is NO RESPECT for the next person and this is not the only company that addresses clients in this manner.
