I recently bought a 2021 petrol polo from Agnews of Belfast had been booked in for a service but in the meantime there was a few lights appeared on the dash I arranged to take the car in earlier 9.am on a Thursday morning got car back 7 hours later but the lights are still on the dash. They say the car needs a new battery which the warranty won't stand over said the car was not getting enough driving I have done 6000 miles in 7 months. By the way £250 for a battery. Any help would be great many thanks
