American Express? Quick call and fraudulent charges are immediately removed.
As such, I spend millions of dollars through American Express and virtually all of my retail shopping through Amazon. I've dumped service providers who don't accept American Express and avoid purchasing countless products not offered for sale through Amazon.
My response to inadequate customer service is as follows. In the name of efficiency I'd recommend the following:
1 - Answer about problem being resolved 2 - Problem not resolved (24 hours) 3 - Inadequate answer 4 - I am sorry I will have to issue a charge back for your failure to deliver on services as represented. 5 - Problem solved, either by me or them.
