This is just my personal opinion and I do not wont to offend you or do you any harm, but please give proton just some time.
but they won’t approve my post after two days.
To be honest two days aren’t that long for a business. It isn’t good, and they can do better, but in the wild world there are way more companies that will let you wait longer.
I requested a refund after a few days of using their VPN because it wasn’t allowing me to bypass a geo block for a website.
And here starts my problem. It is your right, and you can request a refund, but it isn’t good. It will not fix the problem or help you/the devs behind proton.
For a software developer it is pretty frustrating that at the smallest issue people start requesting refunds.
Work with the team together and try to fix the difficulty instead of just grab your money and go.
