HDFC Bank Fastag — non receipt of fastag even after one month hfr094141

Address:

Chennai, Tamil Nadu

I have applied for fastag through online on 17.12.18, paying the amount & necessary document (Rc copy of the car) was also uploaded. Since there was no response till 03.01.19, contacted the customer care number[protected]. They have instructed me to sent through mail pan card & aadhaar card copy, which i did on the same day.
After this i had horrible experience each time contacted the customer care number. They will keep my call on hold for almost 25 minutes & used to say no mail received from my end.
After sending & calling them, someone admitted that there was some portal issue & i will get the tag in two days 07.01.19. This two day has not come yet.
Now they are saying that they have issue with the courier service.
I received one sms saying that my wallet has been created on 11.01.19. But the tag didn't reaach till today (22.01.19)
