LendingClub Repeatedly misrepresented a loan cancellation extension and now are charging me for the whole thing with interest San Francisco California

I applied for a loan with LendingClub. I was rejected. I sought, signed and accepted a loan with a different company and moved on. Until I unexpectedly received an email that my LendingClub payment was going through.. I was confused and panicked, and called LendingClub right away because I couldn't afford both and had acted under the information that I received - that the loan was rejected - and sought another loan. I was told that I could cancel and I began the process of cancelling, and that I needed to repay the initial amount that had gone out to my personal account and my creditors within 30 days. 

I called LendingClub about twice a week after this action to touch base about my cancellation, because I kept getting scary email reminders and I was assured that my cancellation was on track and that I could even seek an extension if my creditors were slow in repaying the amount back to me to be returned. 

My final creditor issued my refund in the form of a check - and it wasn't going to make it to me within the 30 days allotted, so I told LendingClub that I indeed needed an extension. Numerous LendingClub employees assured me over recorded phone calls that I was on track for an extension and that I needed to call when I received the check. 

But today I noticed my first loan payment had cleared from my account - so I called again in a panic to let LendingClub know there was a mistake and that I was still awaiting one final refund. 

And I was suddenly told there was no such thing as a loan cancellation extension, despite several employees assuring me over the past month that there was. 

They're telling me that my only option is to pay the full amount (with interest) and said that they'll deal with the employees who (in my words) "misled" me about there being an extension. But they said there is no such thing and that they would deal with these employees separately, but that it would no way impact my loan repayment. 

LendingClub willfully miscommunicated loan repayment and cancellation terms with me on several occasions over the course of more than 30 days. To my enormous detriment and to their gain - they're going to get a lot more money from me as a result of their lies. 

I would like the loan cancellation extension that was voiced to me as an option and that I was told was requested on my behalf repeatedly over the course of the month so that I only need to pay back what the company initially paid out to me, as several LendingClub employees communicated to me over recorded phone conversations.
