[Resolved]  Clay Telecom — over billing issue

Address: Bangalore, Karnataka, 560100

I chose 2999/- corporate bill plan (Sim plan for my october 2017 germany trip) and i received a bill of rs. 13, 617/- which is a huge overbilling. When i asked to correct it, there is no response from the billing department. I spoke to people like garima singh, vani kataiah, etc and they do not respond to resolve this. I kept sending emails and making phone calls, nothing is done from their side. I need a refund for my amex card deduction which they made.
