Bests & Worsts Reviews from Amazon

I made my July pymt on July 2nd and then they charged me a late fee on July 28th stating that I did not pay the bill. Not only did I pay it but I paid almost 500$. Took FOREVER to get through the automated service, and then I was hung up on by the first person, the second person didn't understand a thing I was saying, the manager on that call said she fixed it, but then she hung up on me too. HORRIBLE CUSTOMER SERVICE.
