Sony India — I complaining against service given by sales person

Address:

New Delhi, Delhi, 110096

I have brought sony bravia TV from Gip mall noida sector 27. The sales person (#GAURAV SHARMA) of reliance retail Ltd told me about the exchange offer but after purchasing of TV he change his statement regarding offers given by him. He stopped picking my calls and he started manipulate me. Such kind of behaviour will impact the reputation of the company. I feel cheated by such a reputed brand. We as a customer create an image of any brand by the services are given. I am highly dissatisfied and disappointed. I will never buy any product of Sony company.
I requested to solve my problem as soon as possible and please provide offers which are valid. False offers will create distrust and dissatisfaction.
