Jeep renegade 1.6 etorq sport is the worst car ever

Worst decision ever I had ever made was to buy Jeep renegade from Jeep Grand Central motors. My Jeep gave me issues since it was brand new and they would say it's fixed. I had transmission failure, oil not supplying to gearbox, Radio, car can't detect airbags and now they say it's a gear box issue. Clearly these are factory faults but all they say I have to pay this and that. Today I'm tired of this nonsense. They need to take their car and give me back my money. Last time they said their manager will call until this day no call
