Axis Bank — fastag not received - no response from customer care

I have booked fast tag on 27th nov 2019. Till date I have not received fast tag. I called to the customer care..they raised 1 SR & inform that I will receive Fasttag before 15-Dec-19 (SR[protected] on 12/11/2019 5:48:56)
I have not received Fasttag then I again called to customer care. They raised another SR (SR[protected] on 12/16/2019 4:14:58) for that & ask me to wait for 48 hours for the resolution. Then I called to customer care on 18th Dec...that guy told me to raise another SR for that...what is this ???? Where is my fasttag ? They are not able to give status of fasttag..they don;t even know fasttag dispatched or not ?...I have paid Rs. 200 to Axis bank as security deposit & facing many problems to get the fasttag even after taking many follow-ups.
