Ideally, your parents would have the option of receiving the SATs directly and then being able to use them. But I'm sure that it can't be because of their age, if it's a problem for young people. But I totally agree with you that the use of the lightning network is great.
Where I live there are 2 payment gateways, which the government and banking institutions constantly boast about. It turns out that on one occasion I went to pay the internet connection bill for the house, besides being the slowest in the world, I tried it with the gateway created by the telephone company to take advantage of the 10% discount; the result was that IT DID NOT WORK.
I used the other one, 4% discount but oh well, there it goes, I checked and it deducted from my magnetic card, but it didn't send me a confirmation message, it's not unusual because it happens often. But I told my wife, okay, I paid.
On the 5th of the following month I had no internet at home, I went to the telephone company, one of their branches near my house, they told me that I had not paid and they disabled the service, I showed the discounts on the card and the concepts, but nothing, for the head office. I arrived, anyway, their comment was: "that gateway always giving problems"
I had to re-contract the service, with all the expenses. I wrote to the gateway support, they NEVER responded. I reported them on X, Facebook, and even on the mother of tomatoes.
The following month a deposit arrived for the 1000 CUP that corresponded, I published on X that the deposit had finally arrived in the internet account. THEN THE GATEWAY RESPONDS SAYING "WE ARE GLAD THAT YOUR PROBLEM HAS BEEN SOLVED"
Tell me something. In my case I received the deposit, others NOTHING AT ALL.
