Lcd not repaired even after paying rs. 10000

&lt;p&gt;&lt;b&gt;Location/place&lt;/b&gt;: New Delhi &lt;/p&gt;<p><b>Name of company/service</b>: Sony </p>I got my 46 inches lcd repaired by Sony authorised service centre and paid them rs. 10000 as repairing charges. But the condition of the Lcd has worsened after that and now they are asking rs. 23000 for again repairing it. These are fraudulent practices from Sony India as they are only interested in money making.
