Amex Credit Card Complaint

Amex Credit card department,

Rewards Missouri

I recently signed up for an American Express card. I have a screenshot of the details of the offer which was receive - membership rewards points after making $3000.00 in purchases in the first 3 months. I spent over $4000.00 in less than 3 months and AME- will not release my membership rewards points. They 've informed me multiple times over the phone that there is a 8 week holding period before these points are released, despite saying nothing about this in the terms and conditions. Today is the end of that eight weeks and they are still holding my points. This feels like false advertising to me. I 'd like to open a complaint against AME-.
