Discontinued my Voipo residential phone number early in 2019 so I no longer have access to Vpanel. I did not port the phone number, so it should inactive. The last few months, I've started to receive spam SMS text messages from sms.voipwelcome.com to my old, non-active, phone number which are forwarded to my email address via the config in Vpanel.

I can't turned off the SMS forward functionality since I no longer have an account and don't have access to Vpanel.

Anyone else seeing this and can provide some way to fix it?
