ignore the negative comments mate. I'd say all options given to you are useless, especially option 3, which tbh looks like a scam? If you have the patience and IT skills, try heading out of Thailand to one of the countries near by.
Jakarta are still doing walk ins and I've heard they are really easy to deal with in terms of resubmitting documents, so that could be your best option.
Double check the visa requirements too as this visa requires substantial evidence that you're doing what you say you're here to do. Trusting agencies when the evisa is only 5 days launched could be very risky, lots of scammers looking to make a quick buck from you.
If you do end up submitting your own application (why not!?) then make sure to triple check your application form, as even an incorrect space error can get it rejected online.
