We have an EDC machine from HDFC Bank having TID No. 41043801. In this many cards fail to transact giving error message "Tracking Error" or "Enter Master Key". Noteworthy to mention that the same card transacts successfully in another EDC machine we have from ICICI Bank.
I tried upteem time to reach to their help desk number 011-42609244 or 011-40781629 but never could get through as it always comes engaged all through the business hours (9:30 AM to 9:30 PM). I tried atleast one hundred times in last one month and every time it comes engaged, I attempted to send them an email at [email protected] which too failed with error message "Unknown address error 550&-#039;[email protected]... No such user'". I shall appreciate very much if any one can help me in reporting the issue to an appropriate place.
