Amazon Suspended My Prime Account But There is No One To Contact

I placed an order for a monitor on behalf of the company. I used the manager's card for the transaction on behalf of the company and placed the order through my own account. However, when I tried to check my order later, I couldn't find it. They cited various reasons like security concerns. I re-placed the order and contacted the seller regarding the corporate invoice. But this time, not only did they cancel the order, but they also suspended my Prime account, which I've been using for years. I can't even access movies anymore. For an order that was approved with 3D Secure and everything seemed to be in order, what more do we need to do? Should we get approval from a notary? Security measures are important, but this situation is truly frustrating. I placed the order here for ₺1000 cheaper, wish I had ordered from the other site. I've never experienced such problems there. Moreover, there's no one to communicate with. There's no live support, and when you try to reach them via email, getting a response entirely depends on their whim. From now on, I'll prefer to steer clear of this platform. Please catch the real criminals, not honest people.
