Hey there
This is actually quite common and has been raised in here before.
Unless it happens every time (your post indicates it is sometimes) then it is down to the company you are calling and their software for their system not being correctly configured.
Other than tell that company (and customer service agents usually won't know what your talking about) not a lot you can do.
