bad mannered

I just recieved a call from a lady from fnb credit card department, she was rude,she didnt even introduced herself,I know I'm owing fnb but I didnt expect such an unprofessional call from such big and respected institution,I mean she not aware what I'm going through. She didnt even let me explain my situation,. I think it would better to drop an sms rather if you know you gonna get emotional with client you dont even know as if this her money I'm owing,I give her ZERO OUT OF TEN for her bad attitude. Its people like her most that let people to rather go do business elsewhere,she deserves to somewhere away from people.
