I tried to pay aggressively on my CareCredit last month, and their website deleted a "0" on my checking account. The company never telephoned or e-mailed me of the problem. They instead charged an additional $58.00. When I asked to speak with a supervisor I received without a doubt the rudest person I have encountered in customer service. "Dawn" would discuss nothing with me, and threatened to disconnect because I asked her name twice: "I already gave you my name at the beginning of the call" she tells me....."I am the highest person you can speak with on the phone."... I asked her for an address to complain and she again threatened to hang up on me..."I am going to disconnect."....Where is the phone courtesy of letting the customer hang up the phone first? Not to mention the outright customer abuse, financially and otherwise.
