No after service

I made a purchase at Russell’s Vosloorus around November 2017, which everything was a success I was really happy with the service I got. However 4 weeks later the couch I bought started weighing in, I mean the couch is only 4 weeks how could it be. Nonetheless I phoned the store informed them of my problem and a lady by the name of Connie said she will log a complain for me two weeks went by no one called me, I phoned and spoke to the manager and he promised to resolve this, they called me later to say they have logged a call till today nothing happened, why do I have to spend money buying with you and also spend money calling ask you to do your job. I understand that each and every business has delays but all I need is follow up but they just don’t bother to call me. I’m extremely disappointed with your after service I don’t think I will ever do business with you, let alone recommending someone to do business with you.
