You pay that fee for my time and expertise to research and answer your question.
If you opt not to continue on with a subscription, then you pay the fee as a one time service.
If you want an ongoing subscription, then the question would be covered under that cost.
You may change/cancel your subscription status from the help page.
I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.
Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. I apologize this is not the outcome you had hoped for, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately. Rating 1 or 2, or not rating at all, does not produce a refund, it only penalizes me for trying to help. Requesting a refund has the effect of forcing me to work for free to help you.
