Poor telephone etiquette

I have received two phone calls from your call center, spoken to the same woman, who on both occasions did not bother to ask me if it is a convenient time to speak. When I mentioned to her on both occasions that I am at work and cannot speak and gave her another time to call me back, she IGNORED me and continued with her phone call. This is poor service from you FNB. I have been a loyal customer to you for a long period and really expect better telephone etiquette . This afternoon I received a third call from the same call center and ignored it due to the lack of respect from your agent that cannot respect what I’ve been telling her - ********** 073.
