I purchased {$280.00} worth of XXXX  XXXX tickets on XX/XX/XXXX via XXXX. The promotional points didn't post so I went and reviewed the promotional terms. I originally overlooked the " Offer valid for purchases made directly with XXXX  XXXX through alaskaair.com '' line in the terms. When I reviewed the purchase on my statement, it lists " Doing business as : XXXX   XXXX. '' Promotional offers can take 2 days to 90 days to post, so I contacted American Express customer service via chat.

90 days past and no promotional points were awarded. I contacted American Express chat again inquiring about the missing points and I was told that the matter would investigated and to contact them again in 10-15 business days. I waited, contacted them again, and was told my purchase did not satisfy the offer as it was not purchased directly with XXXX, even though I was explicitly told my purchase satisfied the offer requirements. I escalated my issue to a supervisor and was told the same thing.
