AMEX Collections. One of seven possible numbers. I'm reporting this number after 28 years of doing business with them. All my cards (3 TOTAL) were cancelled when I bought from one of my subsidiaries LLC's. I refuse to be reinstated and have vowed to educate them on loyalty by alerting the general public ON how they truly treat their longest customer. I did pay the bill so not to harm my credit. I did wait 41 days that was what justified the call.
