Call center woes.

One of the worst and most frustrating call centers I have encountered. Very few of us have got the luxury of time on our hands to patiently sit and wait while listening to the most boring tunes interspersed with a note that "we are currently experiencing high volumes" with no indication whatsoever when our calls will finally be answered. When this does eventually happen if your patience can last that long, you are often transferred to another person or department where the same process repeats itself. Is it not perhaps time for a call back facility or a numbering system to be introduced to avoid the time delays and frustrations.?
