This Website is not opening on VodafoneIdea. WebMaggu is trying to contact VodafoneIdea for more than 20 days to resolve the issue. But VodafoneIdea customer care seems to be inexperienced and have lethargic attitude. They have asked me to share screenshot and change APN etc. several times but have never tried to open and check the website on VodafoneIdea Numbers at their end. If anyone is working at VodafoneIdea and want to help us out may please mail us with your Mobile Number at [email protected] Sorry state of customer (& customer care) service in India.
