I assure you this is a legitimate support service, we help thousands of people with tech and other issues each day.
You can read through all the terms and conditions and review as well where it shows several times through the sign up process that you pay the deposit to post your question and the remainder of the fee you agreed to upon corresponding with an expert.
I'm here to help you and provide you with information to resolve the problem.
You have defective cartridges, there is nothing I can do to magically fix a bad cartridge, they have to be replaced. After that point the internal cleaning will clear out the bad ink.
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.
