I agree. I built PC's for clients (and others) back in the 90's and 99% of our support calls regarding PC's were not PC related but wanting help with learning software we didn't supply. We finally added a message stating "if this phone call is related to software not supplied by us then call them". And that eliminated 99% of the time we spent on the phone. Thank goodness PC's are now available at Walmart !!! While I still build all of our PC's we do not do it for clients.
Our time suckage now is the following. And I know many here have the same issue. We have on our after hour answering system the following. "If this message is tax related please state your name, best number, best time to call and the question". What message do 99% leave ??? Call me back. So you call back. No one answers !! You try to leave a message.. "sorry the voicemail box of the person you are contacting is full" !!! Or,, you leave a voicemail, stating "returning your phone call,.. if you call back and we are not available, please leave a detailed message about your question and a good time to call you". And of course they call back after hours and leave this message. "I see you called, call me back". They see a missed call on their end and dont bother to listen to the message !!! We now call back one time only. Thats it, whether they answer or not. They can call back during open hours. Time suckage !!! Sorry venting before the season starts
