Bad customer service

Once again my purchase from burchmore is disappointing me. the 19th of march marks the second month that I've been driving my Suzuki swift 2012. and This time the car does not want to start and makes a funny sound when i start it. Again i called the guy i purchased the car through and i explain to him that the car is acting funny and has been wanting to be jump started more than four time last week. I called him on a weekend Saturday and he said he was going to talk to his boss about it. I explained that i was not sure what the problem was as it could be the battery Or something more serious than that.Monday i called him to remind him and he said he will get back to me, he didn't. The second time I called and again he said he will get back to me and he didn't. I called countless times after that and my calls were not taken. until the last call he answered. According to him I have been driving the car for 'Long\ and they cant do anything about it. I feel like buying a car from here was the worst mistake i could have made. the battery itself is not secure in the bonnet
