ICICI Bank — non resolution of credit card issue

I am writing this mail with lot of anguish and distress due to non-cordial response from your credit card team since last one month. I am one of the oldest customer of icici bank having saving account and credit card over decade of time and my trust & faith for icici was extremely par that i have not even thought of shifting to other banks inspite of the fact that in our company we are associated with sbi. But all vanishes within short span of time and without taking much of your time just to brief the whole issue which is under :-

1. My platinum credit card was expired vide no. Ending with 2023 and was due for renewal in the month of august 2017 and before one of renewal i requested for the corel card in place of platinum card by visiting the preet vihar icici branch. I have all the correspondence..
2. New card was issued after 15 days with the no ending 3003 but my nightmare started when i received the platinum card also along with add on card. Moreover new corel card was issued without pin no. Meanwhile bill was generated and i could not able to access the bill. So from day one tried for the customer care no. But ivrs system always asks for the pin no., tried to generate the pin through ivrs but message was conveyed that your mobile no is not registered. Even visited nearby banks also and they were adamant that plz talk to customer care only..
3. During this process, bill due date was over and my query about the bill remains unresolved. After the due date and non payment of credit card bill, received call from icici bank insisting to make the payment but i categorically toll first resolve my both the issue i. E. Pin generation & bill amount /access query.
4. They could not gave any resolution but provide me one no and tried this no for continuously & manage to contact the customer care executive first time but again got the very negative that corel which was issued to me is under the name of my wife name i. E. Vijay laxmi hence without their consent pin cannot be generated. I told him that new card is under my name only and but keep on saying that in our record name of ms vijay laxmi is appearing. Then i requested for the escalation officer, initially they refused but after holding the call for 5 minutes able to connect. My problem of pin generation was finally resolved and they provided the copy of bill but they tile me that you have to pay the interest and i keep on requesting that due to my non resolution of issue why should i bear the interest, i pay only the billing amount. They raised the sr with no. Sr[protected] but till date no resolution was given and due to response i have not paid..
5. From last 15 days i keep received the missed call from no [protected] i. E. Icici customer care on daily basis and only once they spoke to me insisting for making the payment immediately. Aggreived with response i raised the complaint using your icici portal at all the three levels but not even a single icici official spoke to me, only keep on received the missed calls.
6. Finally without any resolution my credit card was blocked and till date no resolution has been given.

My only request to the highest authority to intervene and help me to sort out the issue.. I am ready to pay immediately but not the interest part for which only bank is responsible.. You can check the history.. I have always make the payment well in time.

Your icici customer care is so dis heartening and customer focus is almost negative, hence i am constraint to write this mail to the highest authority and expect the early resolution so that association can be continued with you bank.
