*********** and not honouring garrentee

My fridge stopped working in Dec . After being assured that its fixed with words of "I'm not guessing - I know what I'm doing" and a 6 month warrentee on the work done I paid the close to R3000. It worked for a few days and stopped - gas leaks and blockages - I now needed a external condensor fitted...worked for an hour and started tripping the power - it's now March ..empty promises and excuses....
