BAD SERVICE AT DALY LAND ROVER

I took my land rover to DALY LAND ROVER POTCH to assist me with a fault on the car which cause battery power loss,they sent the car back saying the battery is still fine,I must bring the car to them the next day and leave it there for 2 days so that they can work on the problem and that I must hire my own vehicle because they can't assist in giving a courtesy vehicle.After 2 days they contacted me saying the battery is the problem???What happened the first time??Nothing is wrong with the car itself and that I must make a payment of R 1042.30 before they release the vehicle.I bought a new battery and the problem is still the same the next morning,I have to jump start the car everyday since.After contacting them again the they told me to do a service check on the vehicle's tracking device,the unit is disconnected for two days now and the same problem is still there.What makes me angry the most is that the service advisor told me :\Mr Roos
