Blue Shield of California Refusal to Cancel Policy Nationwide

Originally I used BlueShield since I was freelancing. Now that I'm working full time and have the option of using my employer's insurance, it should be simple enough to cancel. However, there's literally no way to find a cancellation option on BlueShield's website. 

When I tried calling, I was on hold for hours until the line simply disconnected. It didn't matter which day or time, there was always too many people calling at one time, so I could not ask how to cancel.

It was only until I discovered they have a Twitter help account that actually provided some assistance. The generic reply was to use a special contact form. The form is useless if you don't provide a phone number for THEM to reach you at their convenience. You only have one opportunity per contact form. After wasting much time trying to get an answer, I get an email from them literally saying that my policy is cancelled effective January 1, 2014.

However, few weeks pass and I get a bill saying I have to pay by June 1st, 2014. There's no getting through to them on cancelling your policy. This is not just affecting me, if you take a look on their Facebook page, you see dozens of complains on every post from other victims saying they cannot cancel either. 

I honestly cannot understand why this company is still in business or even allowed to do this to paying customers who spend thousands every year.
