Almost every time I call a business they tell me they're experiencing a high volume of calls. If, as it seems, that's always true, then they clearly need more operators to answer the calls.
Then they tell you to go to their website. If the answer to my query was on the website, I wouldn't have bothered going to the hassle of calling you and dealing with your byzantine options menu.
And the ultimate insult, "we're too busy" and cutting me off. At least I didn't have to listen to hold muzak.
