Serious issues with Electrical Fitting Circuit

I brought this vehicle  (Grand i-10 Magna Petrol) on 11th October 2013. And its going to be three months. After purchasing, five times I had visited Service Center. Initially the problem started with the Battery draining issue. After the software updation and re-installation of the Battery on 27th Nov 2013, the AC in my Car is not giving good Cooling effect. Since then my visit to the Service cente,  contacting Call center to raise the Compalints, etc etc. After which the service team notice some unexpected noise coming from the Compressor(AC), which is then replaced with another AC compressor. But till now the AC Cooling Effect is not rectified. The interior of the Car is not getting Cooled. Now as per the Dealer it is been notified to the Hyundai Company for the recification. I am now waiting for the Hyundai Team Officials to check,identify and recify my Car AC issue. All my Excitement of buying this Car is now vanished. Waiting for the Hyundai team Officials to sort out this issue professionally. Else I am forced to take the stern legal action.
