"Purchased an SSL but i cannot use it…"

Purchased an SSL but i cannot use it unless i pay to upgrade to the "enhanced DNS" package.
The only way to get the certificate validated was to add a TXT record. But.. “To add TXT records/use the SSL on our ddns.net, you must have an Enhanced subscription”
The only reason i need to add the TXT record is to validate the SSL i just purchased from them! Support staff did not want to help, all to quick to say upgrade or issue a refund.
Absolutely disgusting!
Why allow me to purchase a product I cannot use and bend over backwards not to help?

"be careful with billing"

Although you have auto-renew off, they activate the auto-renew for billing two years without your permission. If you claim they dont refund because "terms of service".

"customer service so awful its a wonder they have customers."

Was using their free DNS service with no issues and so felt safe ordering there pop email service so I could get my business started. for a week I was able to send emails but emails to me were not being received. Their staff eventually got back after a week with a cut and paste reply which was for a different problem entirely. after a could more days of trying to fix this issue when I should be working on ... work. I demanded a refund. They would rather refund then actually provide the service they advertise.

"Great support from Shauna from No-IP!"

Great support from Shauna from No-IP!
Have to close my subscription due to retirement.
She worked on it right away and I got my refund!

"Poor customer service"

Poor customer service. They refuse to actually troubleshoot shoot issues and constantly point any problems at the customer-side, without facts. Avoid this at all costs!

"Scam"

Randomly billed our customer 25€ eventhough we've never even contacted them / heard from the until today. Scam, avoid them.

"I bought a dynamic domain name from…"

I bought a dynamic domain name from noip.com, and the set-up was relatively easy and, at least, worked. I then bought a RapidSSL certificate to secure my domain, and that's where all the problems began. In order to authenticate my domain, they needed to send an email to my domain's registered email address. They sent the email to the wrong address. When I pointed this out, they said they couldn't do anything about the address and referred my to DigiCert to get them to change the registered address. DigiCert told me that Noip – who had effectively washed their hands of my technical issue despite being the reseller – should have been doing this for me. Lots of emails to noip later, I gave up with their utterly hopeless customer support and asked DigiCert to sort the problem out for me, which they did. They issued the key and the certificate, so the site was validated. However, noip continued to refuse to accept this, and they are the only obstacle to getting this otherwise simple process completed. Noip have no idea. If you can get their service to work first off, then you'll be fine. If you can't, their customer support is a complete waste of space.

"I don't have any problem"

I'm using a free NO-IP domain with my server at home. I had no problem of my account being disabled or anything like that. Yes, you need to "confirm" your hostname every 30 days, but that's okay IMO.

"There DNS updates pretty well and can…"

There DNS updates pretty well and can be useful
they added support for ipv6 something that more and more people use including me
except DUC doesn't support it? so now NO-IP is less useful and I may have find an alternative

"Had issues from day 1"

Had issues from day 1. E-mailed them and got pathetic replies. Not very helpful at all. Best ditch them and go elsewhere.
