Ease of use, ease of implementation, nothing else!

What do you dislike about the product?

Occasional connectivity issues, nonsense 137 OOM and infrastructure failure which result in build failures with no part on our end. That costs us credits. 137 OOM error happens from time to time to our Node.JS application when their dashboard resources show that RAM consumption is only 50%. Support engineers do not thoroughly read and understand issues when email them at support@circleci.com and reply me with totally different context about the problem. Just yesterday, my web applications fail to `yarn build` after I downgrade the resource class from xlarge to large. Contacted support but no reply.

Billing is a fucking mess and nightmare! There are duplicate information in the bill downloaded from their website and when I asked for consolidated bill, they just answer don't have it. There is no transparency on how many build minutes and credits I spent each day both on their website and the monthly bill which make it difficult to understand when the monthly bill contains many refill item charges. It is difficult or impossible to track usage and burndown of my subscription and total outstanding refill amounts on a daily basis. For example, I went through the build history for the 3 days into the new billing cycle. There were a total of 74 build and when I sum up the duration of the build, it is 597m 41s. However, their fucking rubbish dashboard shows 4265 "Compute" minutes. Is this a SCAM?
