Other — fastag not received

Hello team,
I bought fastag through online portal of icici bank on 9th dec., 2019 for which account # 22307409 has already been activated on the very said day.
I am trying to connect on the customer care # [protected] multiple times but unable to do so.
I have not received my fastag as yet.
Request you kindly to look into the matter at the earliest and resolve the same.
Looking forward to hearing from you soon.
Thanks
