Worst service

So we purchased a hyundai i10 from hyundai the glen last year and had you guys fit in the alarm on 19th of july the central locking gave up but the alarm and hazards worked so I called the service booking agent thando and booked the car in for its first service and also to check the central locking out it was for the Wednesday the 24th july no please note I had to take a days leave cause I dont have another car which was abit hard to do but I managed to do it so I got the car back the Wednesday went to fetch my daughter I lock the car go fetch my daughter come back and try to unlock it nothing happens opened it with the key and it opens but no alarm so I called hyundai again and i said i can only bring it in Saturday i took it the the saturday and was told that they need the car for 2 days so they can sort the alarm out now the way i see it this isnt my fault as hyundai fitted the alarm so I have to deal with the inconvenience of not having a car cause u guys dont have courtesy cars and the receptionist dont even give anyone messages to call us back no I have to try and make a plan to get my 2 kids to different schools and I have to make a plan to get to work and also fetch my 2 kids from different schools and try and get home just because you guys didnt put a quality alarm and central locking and all I got out of the people at hyundai the glen was ahh we are so sorry .... well this will go on hello Peter cause its utter bull****
