Hi,
I am from hyderabad and everyday i travel on orr from nanakramguda to kokapet and vice versa. On 27-sept-2019, amount of rs.70 got deduced. It is 60 rupees extra than the regular amount. The actual amount that is deduced should be rs.10. I called customer center :[protected]. First of all they never picked my call. After a lot of effort they picked and asked to send the details to "fastag. [protected]@insolutions.com". It has been a week i sent the details and they never reverted back. This is not the first time it happened to me. If it dosent get resolved, i shall discontinue services of hdfc and go for another back.
Here are the details:
Amount — amoun deducted 70. Supposed to get deducted is 10.
Reference number — [protected]
Date of transaction[protected]
Fastag id — custid[protected] — walletid[protected]
I want this to be resolved asap.
