American Express India — no response from customer representative

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201305

During 1 year I sent the application forms 4 times to given address (Gurgaon Cyber city office).

Every time i got the answer they've never received.
Then they have given me the same address and same forms by email.
The same repeated 4 times in a year,
So i made a complaint in the web site, then the person suggested to send a scan copy to the person incharge "prashant mishra".

After sending the scan copy at 2. Jul, again no one respond even i've sent email and scan copy several times to prashant mishra(prashant.[protected]@aexp.com).
Is this AMEX customer care general quality ?
Or is this just that customer representitive person problem ?
