Axis Bank — axis bank fastag not received and no response in toll free number

Address:

Drive in road, ahmedabad, 380052

I have applied and paid the necessary amount for fastag on 22nd December on the Axis bank site. I received a confirmation message saying I will receive my fastag within 7 days. But there is no sign of it up until now.
The toll free number given on the page has been tried several times, but it runs nonstop advertisements about credit card and various schemes, with no one answering the call.
In this period I had to travel twice outside city and wait in long queues.
Please help!
