Amazon uses humans.

The problem is that these humans do not speak English. They follow a template that Amazon gives them when they get the job.

I like to call the support employees "professional readers of the Amazon policy". Its important to note that these individuals have no capabilities at all. The idea is to make it appear like Amazon holds your hand every step of the way to financial success. This is why there are many individuals who mistakenly put their life savings into Amazon thinking its a lot easier than it appears.

If you are looking at this with a bureaucratic mindset, your payroll overhead is decreased due to successfully employing overseas employees(cheaper minimum wage than the United States) as well as increasing income due to increasing the perception that managing an Amazon seller account is a lot easier than it seems.

I would suggest not paying attention to support. If you do, you are at risk of amplifying your problem unwillingly.

I know it sounds counterintuitive to try and self-service your issue when Amazon offers "so much help" but, realistically, its the only option the leads to an actual solution.

I would recommend, next time you have a problem, to write as much detail of the problem as you can. I have to guess what your problem is.

I am assuming you are getting a credit card error that is not allowing you to enter your Seller Central page until you upload a valid credit card. If you are getting charged but you are still unable to enter your account, you will need the help of a moderator with the case ID you have uploaded. It will take some time before a moderator responds.
