A while back, I made the mistake of applying for a Linux fund card. This was not foolish in and of itself, but doing business with the parent parasite was.
I moved, and during the moving process I knew my new street address before I had the new phone number. I filled out all of the "Change of address" slots on my credit card and sent it off, using my cell phone as the contact number.
This was easily one of the dumbest things I've ever done, with the single possible exception of that one fling with a web cam girl, but we won't go there.
A week before this writing, I received a phone call, on my call, from the credit card company responsible for the Linux Fund Card. They pointed out that I was well under my credit limit, and were trying to get me to transfer my balances to their card.
I explained, quietly at first, that I did not want to get any phone calls unless there was a problem. I also explained that this was my cell phone, and that I wanted to be placed on the "do not call list."
The smarmy telemarketer replied with "This is the contact number you gave us sir."
"Do not call me to sell me anything."
"I'm not trying to sell you anything, I'm just informing you of the low interest rate on your existi-"
"Don't waste my time with semantics. You know what I mean. Is there a problem with my account?"
On March 19, I received another call. This one was from the same damn credit card company, offering the same damn balance transfer.
I said, very politely, "I am not interested. I do not wish to be called unless there is a problem with my account or if you suspect the card may have been stolen. If you wish to contact me for any other reason I prefer you do so by mail."
Then I hung up.
We'll see if they call again.
If they do, then I'm about to cancel a credit card.
