Axis Bank — replacement of fastag

I have applied for Axis bank Fastag n also received the same. But unfortunately somehow I have lost the Tag. I have requested for replacement of the same on 24th Dec over phone. A confirmation reg my request was also sent by them through sms n also mail. But till date I didn't receive the Tag. In this regard I have sent 3 emails to Etc.[protected]@axisbank.com but NO REPLY RECEIVED. I called up their Helpline (though its very very difficult to get their line) they assured me that within 24 hours they will get back to me. But NO REPLY TILL DATE. Most Unfortunate to see the servicing of this bank.
Can it be resolved ?
