We may need to communicate back and forth in order to get the issue resolved . I am an independent tech, and volunteering my time unpaid until the conversation is concluded. I request you click the EXCELLENT smiley face once you have all the information you need. It is my intention to solve your problem with a quick, honest, and helpful answer and my goal is for a rating of Excellent Service. If you do not feel I have earned a “10” rating in all areas, please let me know what I can do to meet your expectations.
Should you feel the need to provide a negative rating of Bad or Poor Service, please wait and let me know what I can do to clarify or more thoroughly answer your question. You are rating me personally, not this site or your product and negative rating will not initiate a refund. Please know that not all issues can be fixed online; in those cases of a hardware failure, I’ll troubleshoot and diagnose the problem, and provide a practical recommendation for how to proceed.
My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
