Get an offer for 60, 000 miles from AMEX for Delta? Don't count on it. After spending hours on multiple calls and being told various deadlines ranging from 2 days to 8 weeks. I was finally told by American express that they would not honor the 60, 000 mile promotional that they sent me. Not only have I received one but two of these promotionals and they are only giving me 30, 000 miles. I went as far as contacting the executives at AMEX and they refuse to fulfill the promotion even after they required me to fax a copy of the promotional that I received. American Express needs to do something about this issue or I will be done after completing my $1000 spending. There are many other credit cards that offer good rewards, have good customer service, and do not charge a membership fee. Why stay with them and pay a membership fee when their customer service is unprofessional and their promotions have no integrity. There needs to be a zero star rating so it can be applied to AMEX's customer support..
