Bad Client service

My father bought a tv at bradlows mabopane in November 2015 on the 3rd of December 2015 it stopped working we called them on the 4th of December 2015 they promised to come and have it replaced on the 7th of December 2015 we waited no one came we kept on calling they kept on saying later today everytime we called, they sent one of their consultants to come check the tv he confirmed it was something inside the tv that got damaged and it needs to be replaced (the tv)he called the branch and then told us it would be replaced (the tv)on the 9th December 2015 latest the 10th of December 2015 the 11th December 2015 we called and spoke to the manager but just like his consultants he promised us lies and said the new TV arrived at the store on the 10th December 2015 but they had no transport to deliver it so he will personally bring it the same day(11 December 2015). Today is the 13th December 2015 and we still waiting worst client service ever
