A credit card was issued by Synchrony via Cathay Pacific (CX) email promo on 10/21/22 to earn 40,000 asiamiles when open a CX visa card. Made multiple calls to understand qualification for the 40,000 miles. Card was received with no recap of qualification rules so called to understand them immediately upon receipt. I meticulously calculated my $3000 purchases were spent before the expiry date of 1/19/23, on which date I noticed only 35,000 miles were credited to my Asiamiles account including $2000 spent. I made calls, sent messages and wrote letter with proof of the email promo from mid january up to April 28. Specific dates of calls: 1/25,1/27,1/28 (letter), 2/18, 2/28, 3/4, 3/20, 3/25 (email theclub of CX as per bank's instruction), 3/29, 4/14, 4/28. These were follow-up calls every 10 business days as I was "guaranteed" to receive a letter explaining why I was denied the 5000 miles to my address on record. Yet up to 4/29/2023, no such letter was received and no explanation was given. On 4/28, their account manager Richard said he will issue a letter to request more info which I should expect in 7-14 days. There must be something wrong in their system!
Desired outcome: 1) grant me the missing 5000 miles as promised in the promo (see attached)2) an explanation on why the letter of denial as told by 4 of their customer service reps since Feb, 2023 never reached me!
