Customer support can make a big difference with any online service, especially when a question involves payments or account settings. I usually look for a few simple things: whether the contact details are easy to find, how clearly the reply explains the issue, and whether I need to repeat the same information. Fast replies are nice, but a clear answer is probably more useful in the long run. I also prefer support that keeps the conversation simple instead of using lots of technical wording. For me, those small details say a lot about how practical a service is.
