American Express - Have also started cheating and doing fraud with Customers - Shocking & Wired!!!
I have opted for Amex card in Jan' 2015 and have been asked Amex representative that i just need to pay first year Anual membership for INR 3, 500.
Yesterday when checked my latest statement i came to know that i have been charges extra of INR 5, 000 as an Annual fess. There was no SMS with respect to card fess which has been added to my statement. Today i called up customer care and spoken to CCE all what he has was an apology and he told me that i have signature all the Terms & Conditions at the time of applying for this card.
I re called and could collect that Amex representative who has got my application processed did not ask me to sign any documents in fact he asked me to share my documents over his official email - A copy of which is still available with me. Than i realized that the sales representative would have copied my signatures to get the application process since i will not signed any of the document which has a yearly fess.
Later when i asked the American Express team that share my signatures or a scan copy of application they do not have it since they will be at fault.
I asked American Express to cancel my card they were very quick in doing it since they do not want this matter to be highlighted since they also no my signatures are been done on application form without my authorization.
Pls stop doing this fraud activities dear American Express
