I work at a major international company in mid-level management. My department has about 500 employees scattered globally there are probably 20 people at my level with different areas of responsibility. I have been working at my company for over 13 years and have held 6 or more roles/titles. For the last 6 years, I've been using a very generic title because I got tired of having new business cards printed... example Director or Marketing. My name and contact information has been sold to companies with various versions of my different titles. I receive at minimum 2 cold calls per day and 5 or 6 emails soliciting business.
My problem is when one of these cold calls goes like this which is about 75% of them:
Me: HMMMM Last Name
Caller: Hi, is this HMMM Last Name?
Me: Yes it is.
Caller: Hi, How are you.
Me: I'm well.
Caller: That's good. Did I catch you at a good time?
Me: May I ask what this is concerning.
Caller: My name is X and I'm calling on behalf of 22 company.
Me: OK, how can I help you?
Caller: 22 comapny provides blue, yellow, and green services and I'd like to discuss how we can do business with your company.
Me: I'm sorry, I'm not responsibile for those activities at my company.
Caller: continues to explain how 22 company can provide value to us.
Me: I said I was not involved in those activities.
Caller: Well, your the Director of Marketing, aren't you?
Me: Yes, I'm one of several but I do not have those roles.
Caller: Well, what do you do?
By the time we get to this point in the conversation, I'm irritated I've spent 4 or more minutes already on this conversation and that I now feel they are challenging me about whether I'm telling the truth about not having those roles. I'm also irritated that they have researched so little about our company that they wouldn't understand that we would have many Directors f Marketing, not just one.
These bolded statements are word for word responses I get on at least half of these conversations.
Normally I answer a few more of their questions and try to politely disengage. I do not provide contact details for my peers. But this morning I was not in a good mood and my response was "Why are you challenging me on what my role in the organization is? I said I am not involved. Goodbye." and I hung up.
I don't want to be rude, but I'm loosing patience.
Any suggestions for different phrases to use to get it across earlier in the conversation or to accurately convey they are wasteing their time and mine?
