Help me with my question to recharge credits

Greetings for everyone and thanks in advance. I am new to this community and I would like to support you by buying what you offer but I need to recharge credits and for me that is confusing.

I know there are tutorials like the one here https://kichhoat24h.com/buy
but honestly I don't quite understand, although I understand it, English is not my native language and although I use a translator, it changes the words and it is confusing to me.

Could someone guide me?

I have Binance and Paypal

I think I wrote to an administrator but I don't want to bother or break any rules. Sorry if this is not the right place for this type of query.
