I was very much unhappy with their service. About a month ago, I was shopping in a local telecom service center for a mobile phone, but my American Express card got error all the time. I didn't owe them a penny and was wondering what's wrong with it. After calling to American Express, and after 15 minutes stand-still in the shop with a dozen eyes on me, I got a reply that it's just their system error.

Now, I got their statement to charge me for the annual fee which I do not think they worth it, I told them just to cancel my card as I seldom use it. They do not apologize nor try to convince me to use it, try their service again, the customer service officer only said that should I cancel it now or in month end?

Could we call this a service?
