Woah Sir...

Dear Mr. Vendor Rep,

I'm sorry that you had to wait on hold and be transferred a few times before ending up with me. However, in the future, you should listen to what I'm asking before you throw a 3 year old tantrum and hang up on me. Because now you aren't any closer to getting your needed quote.

Love, Elisha

(Luckily for him, I'm feeling nice, and slightly humored by his tantrum, and found his appropriate sales team and had them send him an email to get the information we need to write a quote for him.)
