Thing is, I can totally see why they avoid calls or cut calls off! I used to work in a call centre, and the general public do not listen to you.
You begin explaining something that will have a positive resolution at the end of the sentence, however you never get to the end of the sentence as the customer keep inturrupting you with their presumptions of what your about to say!
Or they blame you for absolutly everything. "It's your fault my direct debit bounced", "I never got your letter", or when things are really looking bad for the customer, they used to come out with "but I'm disabled".
If customers would stop trying to be the boss on the phone, things would be ALOT different. If they would listen and present themselves in an adult manner, call centres wouldn't have so much bad publicity - the customer phones up and will not listen to anything thats being said - thus annoying the call centre operative - hence nothing being resolved!
I used to just stay silent. If I got inturrupted, I'd continue to talk over them as I was the one who began talking. If they miss something I said because they inturrupted me, it's their fault!
