I used their service for years I used their service for years. Probably paid them over 500k over 18 years and while expensive, the service was fine. Then I tried to stop the service. They ignored my cancelation requests and continued to bill me. Then they had the audacity to put me in collections. Avoid these guys. They're fine until they screw you

You do VERY well You do VERY well. We continue to be pleased with your service. One small issue: somehow somebody has your customer list. I get emails that claim to be from you that ask me to volunteer information -- it is clearly fraud. I do send these on to you -- and now I've added your "abuse" address to my files so I can quickly pass it on to you.

Rackspace was a nightmare Rackspace requires you to use specific hardware and migrate to newer equipment every 2 years. Every time you do rates increase. For us this was extremely disruptive. Migrating off Rackspace was very difficult. I gave notice, then was told Copying our data was extremely slow. I suspect they throttle data transfers. Getting a copy of our data on a USB was ridiculously difficult and took forever. Their trouble ticket system is annoying. Simple issues have to be referred to various departments. They required us to pay via ACH but then made billing errors. I still have an unresolved billing issue. They started closing tickets if I didn't respond immediately. Now they have terminated my online access to the support site and I no longer have access to the trouble ticket system.

Business email crippled while we waited a MONTH for support I’m writing to make sure nobody has to endure the terrible customer service that I recently got from Rackspace. I moved my company’s six email accounts there two months ago. A short time later, a malformed auto-reply email started self-replicating (which a properly-configured mail server should not allow). I quickly contacted live chat (since it took Rackspace support FOUR DAYS to answer my first support ticket), but they were unable to delete the runaway email. I submitted a ticket on August 5. The bad email quickly replicated over 250,000 times and crippled my email client. After five tries their back-end support team finally fixed the problem on September 1. It took them AN ENTIRE MONTH to repair a problem that should take a good admin five minutes to fix.

Repeated spam calls - never deal with Repeated spam calls after asking them to stop on multiple occasions. They offer spam protection, but can't even control their own sales team? Would never deal with them.
