Amazon Prime Charged After Cancellation – $139 Refund Request

I am writing regarding an unwanted charge to my account for an Amazon Prime subscription that I believed I had already cancelled. I had signed up for Amazon Prime and then cancelled the plan because I did not want to continue the membership. Despite this, when I checked my account this morning I saw a new Prime charge of about $139–140, and there are pending Prime-related amounts in my transaction history. I do not remember the exact date I cancelled, but I did not intend to keep the membership active or to be charged again. I request that my Amazon Prime membership be cancelled immediately and that the $139 annual charge (and any related pending Prime charge connected to this renewal) be fully refunded to me, as I did not wish to continue the service. I kindly ask you to review my account, stop any further charges, and process the refund as soon as possible.
