Appalling service on a simple matter

I have just penned the following email to GEICO. Since 12/31/08 I have been making a simple request: send me documents showing when my father was included on my policy, and how much his coverage was. They have again and again sent me (and my dad's new carrier) forms that make no mention of my dad, what dates he was on my policy, or what the coverages were. A gigabyte of email and several hours on the phone have delivered the wrong documents again and again. Here is the email I'm sending them today:

GEICO:

I have been in touch with you since December 1, 2007, regarding getting documents I need. This has not been done correctly.

I have communicated with you via email on the following dates:

Dec 31
Jan 2 (four times)
Jan 4 (twice)
Feb 25
Mar 18

I have also made numerous phone calls, the latest a few days ago.

Nothing has been done correctly.

This is the request I have made many times:

"Hi Geico. I recently requested a document showing when my father, Hans Bauer, was insured on my policy, and what the coverages were. I need to send this to his new insurance carrier, so he can have evidence that he has been continually insured, without a break.

"The document sent to me only showed the current policy, which does not list my dad, who has recently been removed.

"I need a document showing what dates my father, Hans Bauer, was insured on my policy, and what the coverages were.

"Thank you."

A document saying WHEN my dad was on my policy, and what the coverages were, has to go to [Dad's new insurance company, including rep's name and fax #].

Is there any way this can be done correctly, or should I just give up and switch from GEICO to another insurance company?

[my name and policy #]
