I have a conflict when I call up helplines/customer services....
I worked in a call center for 8 years, it was hellish n brutal, and damned good fun! It all depends on which company I was representing. The call center was an OUTSOURCE company, we represented several BIG companies, including government helplines (swine flu, test calls to British Embassies (make sure emergency procedures were solid), UK passport office).
Back to calling up myself! Due to having done the above, I know how I EXOECT to be dealt with, as it's the way I dealt with customers/clients etc. So my expectations are extremely high, but rarely do i get that from STANDARD operators. Now add to that terrible disappointment with my mental health, and my calls can get quite interesting!
So I usually go to ceoemails.com and search for the CEO/director of a company, and calmly (sometimes (quite often) use sarcasm, and use their own mottos/taglines against them) write a strongly worded email. I try not to call up, if I can help it. lol
