Dear sir/madam
I was travelling from patiala to chandigarh on 21/09/2019. When i was crossing to ‘azizpur toll plaza’ at 8:25 am, then operator give me that my fastag card is blocked due to insufficient balance is rs. 106.25. After this i pay rs 50 in cash and take ticket no.[protected] for up and down at booth no lz4. Next i come back from chandigarh at 5.30 pm on same day and crossed toll plaza with same ticket after 10 minutes i was shocked, when received a message on my mobile that “your fastag a/c has debited for rs 35 for transaction by vehicle no pb31m1313 at dharer azizpur toll plaza on[protected] t 17:30:44. Balance amount is 71.25 hdfc bank ltd.”. Now i want answer if my card was in morning then how was unblocked in evening with same balance on same day.
I am dissatisfied from your service i pay doubled charge at single entry. I asked to toll authority about this but they didn't listen my complaint.
