I purchased a change to my account in error.

I purchased a change to my account in error. I purchased a change to my account not knowing I was upgrading to a different service, one I didn't need and that I purchased in error. I immediately contacted pdfFiller and spoke to Kara. I explained my situation, and within minutes, she reverted my account back to the basic service and issued me a refund for the difference. She was extremely helpful and I'm extremely satisfied.
