DTV reset- land border

I have a DTV and am using a land border run company to go to Cambodia. I actually have been in Thailand less than 90 days on a visa, but I am planning to exit because I did not get a visa for my young child, who entered visa-exempt. I did not get the DTV for her at the same time I did because I don't plan to use the DTV much longer than a few months at a time. I am using the land border company because it is the most efficient way to get a new entry stamp. However, I've been informed that the border agent has never encountered a DTV visa and will charge an extra 1500 baht for an entry stamp for 180 days. Their reasoning is that an entry stamp for a longer period should cost more than the base fee . I objected to this but the visa company says they cannot override the border agent's decision. I may just overlook this as unfamiliarity with new visa and pay it to avoid any problems. Just looking for advice on this or advice on if it is even a good idea to get a new 60-day stamp this way.

Hi everyone, I just got some information from a visa company…

They informed me that I should have applied for DTV from my home country before coming here. However, since I’m already here, these are the options available to me now.

What are your thoughts?

Here is the service option

1. Applying with Thai embassy in US. This is required the applicant to be there while we submit and process til visa approved. This service fee will be 10,000 THB ( not included for Thai embassy fee )

2. Applying with Thai embassy in Laos. This required the applicant to be there for 2-4 days. The package price is started around 60,000 THB - 150K THB. The price depends on how qualified the documents are.

3. Applying with Thai embassy in US while you are in Thailand. This service fee is 20,000 THB ( not included for Thai embassy fee ). With this condition, you might face with 2 risks which are flight ticket request or interview in person at Thai embassy.
