Karbonn Mobiles — Service center cheated me

Address:

Alwar, Rajasthan

I had gave my phone A90 Black colour to the customer service centre Chhabra Telecom in Alwar many times. The mobile has stayed in the customer service center more then to me still I face phase problem every month. About one and a half month ago my mobile became dead so I gave it to customer service center and they kept my mobile and the battery claiming to return me in 3 days. So after 4 days I went to them they said one month as the mobile has gone to head office. Now when I went to receive my mobile they returned me a old white coloured mobile and claiming that the set has come from their head office and even not returning the battery. The company is really making a fool of their loyal customers. They even not gave me a job sheet so I cannot tell the no.
