RBL Bank — without receiving card credit card charges

I venkatesh munugala have applied for an bajaj rbl platinum credit card on october 26 for which annual charges are 500 but i have received super card for which annual fee is 3000. I didn't accepted the card from courier boy. After 2 days rbl bank has sent me credit card bill of 3538. They keep on sending mails and messages to my phone for which i don't even know the credit card number and pin. I requested and raised a ticket through mail but no response. The customer care number never connects. Even the rbl bank jntu branch hyderabad are unresponsive. They are saying that we don't have any credit card department here. Due to continuos mails and messages of bills i have lost 25 credit score of my cibil score. I request to please take an action against rbl bank.
