Axis Bank — fastag - most fraudulent behavior of axis bank

I have purchase fastag from axis bank on 27th december 2019 but still i haven't received my fastag.
The issues i faced is as follows-
1. First my saving account is automatically deducted rs 750 on 1st january 2020.
2. I have tried to several times to contact their customer care but their customer care number isn't working or fake.
3. After few days of trying to contact on their customer care i have email to them on etc. [protected]@axisbank.com on 10th january received their reply on 15th january. They provided me a bluedart courier pod number [protected]. When i check this number on bluedart traking it shows record not found. After few days this pod number shows record which is definitely not related to my fastag.
4. After that i have email to etc. [protected]@axisbank.com 4 times but they are not replying.
5. Their customer care number isn't working or fake.
I have still not received my fastag till now.
Now i am totally helpless.
This is the most fraudulent behavior done by any organization.
