Matrix Cellular — Overcharged matrix payment and sheer misbehaviour of matrix employee ms. Ghazal siddiqui

Address: 110030

Website: Matrix Cellular Services Private Limited

My Name is Shashank Gupta and I'm complaining about the Matrix Cellular Employee.
I've given the credit card details at the time of purchasing the sim to charge the amount from the Card as the norm of the Matrix Company. The company is charging more amount as stated and the employee of the company Ms. Ghazal Siddiqui has no sense of talking to a customer. She is calling me as well as other family numbers and talking all rubbish with them, insulting them and cursing them. This is totally not acceptable. First of all charging extra from promised and misbehaving from the family member that too my mother. When I asked her to apologise, she said now I've talked to mother, if not paid, I'll call other family numbers as well.
I want to register the complaint and if not fulfilled by the company, I'll take this matter to consumer forum.
