But:
I'm starting to think you're mixing up testnet3 and testnet4: your Beta guide linked to several testnet4 faucets, which made me think that's what you're using, but other parts of the guide make it look like you're using the old testnet. You should probably use the most recent version, which is much easier to get.
We are using BTC Testnet v3.
Oh I see now.
I sent Bitcoin testnet4 for Bridgoro exchange and I didn't know testnet3 was still active

All faucets I used to get free testnet coins also had only testne4 coins, and I didn't notice any mention
ofabout this in best test ANN or in bridgoro.gitbook page.
