Dear John: I have a problem with my new Dell computer. I can’t seem to get a human on the phone to help me resolve it.

Can you provide more details on what to do to solve my problem? G.L.

Dear G.L.: Look, I don’t want to pick on Dell. But any company, no matter what it sells, should pick up the phone and handle customer complaints promptly and courteously.

Here’s what I’ve learned to do if I have a problem with a purchase.

I track down the number of the company’s corporate headquarters and I call the CEO’s office. I’m not saying that I do this as a journalist. I do this as a disappointed consumer.

I’m polite. I explain my problem to the chairman’s assistant — who, we all know, is really just a telephone operator in disguise. The assistant will give me the name of someone who can help.

Then I’ll start the next conversation by saying, “Mr. Smith’s office told me to speak with you.”
