Telemarketers, and call centres that take your calls are two different things...the telemarketers who ring you up & try to sell a service or a product are often good at what they do - because often how much of the service / goods they sell, determines how much pay they get!!
If you have ever tried to ring a Government department, or a Bank, Insurnace Company, or some emergency services and tried to sort something out with them....sometimes the person you speak to knows exactly what you are talking about, and is able to sort out your issue / query, while others have no idea....
My experiences with another emergency service call centre is terrible... I have had great difficulty in getting my message across, and other times, been on the receiving end of the call centre info, and it has been appalling.
So to have independent answerers in a call centre for emergency services is OK...BUT the training has to be top notch, so the services get exactly the information they need (which of course varies from service to service....!! )
