Hyundai poor service

I bought an I20 automatic in less than a month, the battery died and when I called road side assist at 6am in the morning (2015/10/05) they only answered the phone at 08:00 while they claim to operate 24/7/. By then I was in Rustenburg and I had to go to work in Pretoria. From there the people to tow the car only called after 45 minutes after speaking to the road side assist people. I'm disappointing in their services, it is just too bad. How can you sell a car with a dying battery? and as for taking forever to respond, its unacceptable. Hyundai road side should stop lying about operating 24/7, because they fail to do so. I wouldn't advise anyone to buy their car from Hyundai. The sales rep's service was bad as well, i only bought the car because i liked it.
