Although there might be other means of contacting Amazon customer support, the simplest way is by using the "contact us" page of the company.
1. The first thing you should do is go to https://www.amazon.com/gp/help/customer/contact-us/. This link will take you directly to the official "contact us" page of the company.
2. If your issues are not too big, consider selecting the "Start chatting." Doing this will launch you directly to a messaging platform where you can chat with an Amazon representative, but remember this option is for those with simple problems.
3. There is a list of options you will see in the chat window; all you need to do is to select the one that summarizes any problem you might be having.
4. You can also connect to an associate via the chat window. This option should be used only if you didn't find step 3 helpful.
