I wanted to contact Support of Letsmonitor.org. From information on their website I've found that they have e-mail address support@letsmonitor.org . I've sent email there with my query but received error autoreply
that suggest that support@ doesn't exist on that server.
Error code from that email
Reported error:
550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient support@letsmonitor.org not found by SMTP address lookup
On my bank statement their payment appears as staylive.com, so I tried contacting them but didn’t get a replay, I tried both direct email and the live chat on their website, nothing! In the end I went to my bank and canceled the direct debit directly.
