Jaquar — Bad service and bad quality products

Further to previous complaint...now today I received a call from virat sales centre saying that the technician prakash malik who visited us has made a bill of only Rs.145 with the company...when clearly I have a bill on their letterhead for Rs.1725..On further asking about how can this be done he said that the technician was found of some other fraud and removed...isn't this a case of pure cheating...I had registered a complaint with the customer care and got the work done from the registered service centre... shouldn't the company take responsibility for it...
