ICICI Bank — customer care executive

I have tried to reach the customer care executive and after waiting for 5-6 mins everytime the executives refuse to talk by complaining that my voice is inaudible which is completely ridiculous and frustrating. This has happened to me for 3 times at a trot. I don't understand how silly they think of their customers when they put forward such lame excuses. Fortunately this was my first encounter with icici and definitely the last one. Very disappointed!!
