How to call the IRS

I live in Southern Mindanao 5 km from a good cell connection but there is a usable connection available here at home, and I'm able to receive calls from a friend in California on my cell phone at home. We can't get a landline here even though we're only an hour from Davao.

I dislike phones so have never learned how to use a cell phone unless I really have to, don't even own a smartphone. My son has one and knows how to use it, but nobody I've asked knows much about calling the US, and nobody knows about calling the IRS. Maybe even the IRS doesn't know how to call the IRS, and who would want to?

I didn't receive my first EIP from the IRS of 1200 USD since the mail was stopped completely and whatever was sent never arrived here. Because of that I set up a direct deposit and that's why I got EIP2 and EIP3. I tried for the refund on the annual tax return which was supposed to do the trick but they said I'd already been paid, so I sent the paperwork Form 3911 by snail mail and months later (yesterday) I got a letter from IRS stating they would issue a replacement check but only if I  call them at 1-267-941-1000.

I went to Philcomm and asked how to call the US and the nice man said just put P500 load on the cell phone and call the number. I might have to go back to town with my records to actually make the call, because all I get is 3 beeps. It's so noisy in town, I was hoping to do it from home. I don't even know how to turn on speaker phone, although I can figure it out. Actually I think I was only getting 3 beeps in town too, but I couldn't hear.

This will be the first phone call I've tried to make to the US, I don't even activate my own debit cards since my sister in the US can do that for me when they arrive.

If I go to town and keep trying, is there a chance that I'll get through? I think the 3 beeps mean a connection can't be found. I could buy a phone card and call from a landline at Philcomm but not when IRS is open. Is someone going to answer the phone or will I be on hold for 20 minutes or is it just a menu to push buttons? Anyone know? If it's just a menu and I can do it when Philcomm is open and IRS is closed, that might work. But I doubt that they will reissue my EIP without speaking to me live.

Suggestions are welcome, especially if you've actually had to call the IRS. Last time I called the IRS was maybe 20 years ago and it was traumatic, I still remember wanting to reach out and strangle the incredibly arrogant young fella whose day was ruined by having to serve me. The right solution would be for the IRS to make it easier for people to contact them from other countries, but I'm not holding my breath for the IRS to do anything right.

Looking at https://www.irs.gov/individuals/underst … -or-letter I see this:

"Contact us: We provide our contact phone number on the top right-hand corner of the notice or letter. Typically, you only need to contact us if you don’t agree with the information, if we requested additional information, or if you have a balance due. You can also write to us at the address in the notice or letter. If you write, allow at least 30 days for our response."

What if I mailed copies of all the correspondence so far, explain that they snail-mailed me a letter and check which never arrived since snail mail was not running to the Philippines when they did it, and explain that I can't get through on the phone? Will they do the right thing or not? Anyone have a clue? What other documentation could I send to make them stop dragging this out? I need a roof on my house.

Thanks.
