Lol TBH while this sucks it's hard to have any sympathy. You chose some weird ass off brand ISP. A company that even I, someone who is in IT has never heard of, did absolute zero research before dropping money. Then to top it all off you didn't go through your bank to attempt to get them to handle it and get your money back or at the very least charge back the fuck out of them?
You had so many chances here man.
