[Resolved]  ICICI Bank Credit Cards — Not able to update communication address & poor customer service

I have been trying to update my office address for my ICICI credit card for the past 3 months but of no avail. The customer service call centre for ICICI Bank offers very poor services. Whenever I put forth my problem regarding address updation they listen to it for a while and blatantly cut off the call in the middle of the conversation. The address has to be updated from the phone banking service. The branch people do not entertain request for address change. So I am left with no option but to keep on calling these people to change my address. I would strongly urge people not to use ICICI Bank credit cards. They offer the worst services in the credit card industry.
