There are a lot of bitcoin QR code creation tools but which of them are secure, and create a genuine qr code?

Thank you

Unfortunately, the service has problems and nothing is said on the main page about it.
It is receiving money and does not send them towards.
I've sent coins and they didn't come to a receiver.

To service:
I've sent you 100% clean and absolutely legal money, the service was used because I am not comfortable sharing my financial relationships with everyone on the Globe! Your service has the lowest fee and that's why it's the best choice for mixing clean and legit money.

I owe this money to another person, a legal partner, please refund them asap to a wallet they came from, or send them forward to a receiver, or tell the time when the problem is expected to be fixed.

I have a letter of guarantee digitally signed by the service.

Thanks.
