[Resolved]  Philips India - Hr 1350 Hand Blender — The press switch gets clogged very often

I purchased the Hand blender in March 2006; Within three months the press switch got stuck; It was referrred to the Dealer who got rectified it free; Again aftet TWO months I got it repared thro Philips Authorised Service Centre---Marina Electronics, Chennai-5; They charged me Rs 50 /-; It worked for three more months; Again it was serviced by the same Marina Electronics; I paid Rs 70 /- this time ; Now after three months the same problem has come; I think either the design of the press switch is wrong or the quality of the switch or the servicing is poor ; Who will take care of this ?
