ICICI Bank — Credit Limit Increase Issue

Hi,

I wrote to the Head of Credit Cards of ICICI Bank for an increase of Credit Limit of my Coral Credit Card ending with 2006.

Subsequently a SR (SR[protected] was raised and I was notified about the same on 27-Jul-2020.

The above SR was closed with the below comment - 'As per your request, Credit limit on your ICICI Bank Credit Card XX$CC has been increased to INR 180000 on 29-Jul-2020.'

I have attached the proof for this.

Today, on 30Jul-2020 I logged in the ICICI Online Banking Portal to check another SR and I was shocked to find that my Credit Limit was reduced to INR 120000 without any prior intimation.

Shocked, I contacted the Customer Care and the Head of Credit card. No response from them.

Wanted to check whether Banks are authorized to reduce the Credit Limit after offering a figure without prior intimation and that too within 1 day of offering it?

I have attached 2 screenshots - the first one shows my limit increased to 180000 INR and the second shows that it is reduced to 120000 INR.
Please help me with a solution for this.

Thanks
