I am having credit limit of Rs more than 4L on my Amazon pay ICICI card. Generally I used to keep limit in between 5-10k. I made a transaction of Rs 28k by setting my limit at 30k and reset to 5-10k again. In this scenario I was charged over limit charges. After following many times with customer care, charges were waived off and I was told that it was the last time waiver. I was informed that when I had spent around 28k, the set limit should not be below 28k. It was very strange for me.
