Fastag — incorrect billing using fastag

Address:

Hyderabad, Telangana, 500097

Incorrect charges were billed to my fastag account while commuting from Gachibowli to Rajendranagar. Usual charges for return travel should be 50% less (RS.10) instead, my account was charged with RS. 60. The travel date is 01/04/19 (23.10.11 hours). There have been numerous such unnecessary charges and did report the issue on the Fastag app without any response or history of issues reported at App. I am attaching the screenshot from my mobile which shows the details for the charges. I need someone to take a look at this issue and sort out the issues with the additional charges along with the re-imbursement of the addtional charges from my account
