Hi, I've received two transactions (about 0.45 and 0.8 BTC) while I wasn't looking at my wallet with a difference of 5 hours. The transactions were sent as payments of my services from a customer. The transactions instantly were forwarded to some unknown to me addresses even though my computer was turned off at that time. The first transaction was forwarded even before it got confirmed in electrum. The client sent transactions from Binance.

Here's my wallet: https://blockchain.info/address/1HSnJR4qm3TT8FPgy9BRthYDLh1fcKGNPp

The second wallet was previously mentioned in scam accusations.

Now I'm not sure if I should release the services to the client or what to do. Please advise what would be the right decision.

note: I haven't used the wallet in over a month
