WF-3620 Print Head will not fully clean, see more

Hello! I will be so thankful for any help at all.

My Epson Workforce 3620 stopped printing clearly, with words in a Microsoft document printing with lines through them and spotchy to where you can't read some sentences in a full document.

It randomly started doing it so I replaced the ink cartridges and it has continued to do it. I know how to replace the ink cartridges as I pulled off the yellow "Remove" sticker and kept everything else, of course inserting it with the top-label side facing me until I heard a click.

I have used the "Maintenance" settings multiple - and by that I mean, roughly 30 or so - times of each Print Head Alignment (vertical & horizontal), Head Cleaning, Nozzle Check, and the roller cleaner option.

At first, I called Epson Customer Service. The person walked me through the maintenance steps, though I had done them several times, and told me that it must be the ink cartridges so they sent me all new ones free of charge. When I put them in, the issues were still happening and I ran through the maintenance settings again. When I called Epson back and provided a reference number, they had no idea what reference number I had and had me running through the maintenance steps again though I had assured them it was more than that, I work from home, need to get it fixed. I swear to you, this lady insisted that I must re-try the maintenance settings after already doing it one the phone with her and telling her that I did them on my own. There are no Epson repair centers in my area as well.

Has anyone else had this problem? Do you know of anything I can do? I am not really able to just buy a new one, since i just bought this one in December of 2017.

Thank you
