Axis Bank — Not able to activate my axis credit card

Hi,
My name is Sharan Kumar Chand, I applied for flipkart co branded credit card from axis and receive it few days back and trying to generate a pin and activate my credit card. I am unable to do that for past 5 days because of invalid credentials error.
I followed the steps provided and sent an SMS to generate my first time user credential to login into axis bank net banking. Everytime I try to login I get invalid credentials error. Getting this error for both registered mobile number as well as new generated first time credit card customer ID. Tried using the phone banking as well to generate the pin but there also it's getting rejected because of invalid credentials. I am entering the correct credentials but it's rejecting with invalid credentials every time. I have the physical card with me but I am not able to use it because of this issue and there has been exactly no support from axis bank to get this issue resolved. I tried reaching out to them over twitter and got response initially but afterwords they raised a complaint number : 70059158 and after that there has been no response from them. I have been trying to reach out to them beg them request them for some support of not support then termintate this credit card so that I can apply for some other bank credit card but no there has been no response. Please help me here.
