I need to prove I was using my ISP at a certain period: Last year from Feb 2011 to Aug 2011. Is there any log on my PC ?

When you contacted Customer Support at your ISP and asked for those records, what did they say? – Bon Gart Jun 30 '12 at 22:01
Well it is them I am having to show I was using their services. It's like the first of my 6 months Internet use never existed and when I moved out I threw away my ex bills and contracts. I am in Thailand I signed two consecutive 6 months contracts. Now they are saying I only ever had one that started the last 6 months for one year and they ask me to pay 6 months extra of internet to honor the 12 months. They say they have no record of my first 6 months internet use with them – Anne Jun 30 '12 at 22:16
How did you pay for this service for the past year? – Bon Gart Jun 30 '12 at 23:49

I received bills that I took to the 7/11 to pay. I unfortunately got rid of all those bills and contract when I moved house. So I have no proof and they say they have no record of a previous contract, nor could they find any bills for that period. – Anne Jun 30 '12 at 23:58

If you signed a second six month contract that also required you to maintain service for 12 months, then you extended your 12 month requirement. Even if you had that first contract, your second contract would still require you to have 12 months of service from the date it took effect. – David Schwartz Jul 1 '12 at 0:27

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

E-mails you received, or sent to other people, will contain the IP address of your ISP's e-mail server, proving that they passed through the ISP's network. And for e-mails you sent, they will contain the IP address that was temporarily issued to you, which will be part of the block controlled by your ISP.

To see this information you need to inspect the MIME headers.

Also, if you used an online financial site, such as online banking, it is likely that the web server recorded your IP address.

In the end, your computer is the last place you should look for evidence, because it's under your control and might be tampered with. IP address logs in the hands of other companies are much more believable.

@Anne: It would have to be an email you sent. Not an email you had some other service (such as Hotmail) send for you. – David Schwartz Jul 1 '12 at 0:56
Oh You mean I would have had to use the mail service provided by my ISP ? I did not unfortunately ... Any other options ? – Anne Jul 1 '12 at 1:14

Above here is an email I sent with hotmail, it has my IP and when I looked it up, it gave their server's name : asianet.co.th. Would that be an evidence ? – Anne Jul 1 '12 at 2:02
