It was through the link at the bottom this guide.

So definitely a scam?

Hey there,

I'm pretty new to this process, so apologies and please tell me if I'm not explaining anything clearly.

I sent my btc to the address provided by Helix using Electrum, but have seen no sign of it returning to my wallet. The Helix Status Page still says Waiting for Payment, after 11 hours. The delay was set randomly to 2 hours. I re-checked the address at the top of the page and it was sent to the right one, but since 8 hours have passed since making the transaction, when I refreshed the page the address updated to a completely new one. Nothing else about the page has changed.

Transaction details:
Amount: 22.97056 mBTC
Size: 192 bytes
Fee: 0.00898 mBTC (4.00000 sat/byte)
Status: 75 confirmations

Am I worried about nothing here or has something gone horribly wrong?
