Customer service post sales non-existant

I bought a couch last year in February with high " quality" expectations as UFO is a reputable brand and largely known for its quality furniture, i was highly disappointed when a R15k couch suddenly started making funny noise when we sat on it after 3 months, i then went back to lodge a complain in-store "Menlyn", i was then told to send pictures of the couch to the sales person, i still felt like i wasn't given proper attention and it looked as though i was a pain in the **s, i went back to buy a bed in July (showing my belief in the store) and raised the concern that i was still with a faulty couch and no assistance given to me. i then called UFO head offices cause clearly the store branch in Menlyn was not giving me proper customer service, they are only good with Pre-sales and during the actual sales, post sales is not their baby. The head office then instructed that i send them the pictures to an email address, that's when they arranged for the couch to be picked up. I then questioned that it must mean the couch had a factory fault in the first place hence it only took 3 months for the defaults to appear, i called so that i can voice out my concerns and tell them i preferred a new couch since it was still under warranty, they shut me down as though i didn't pay with my money, the manager in question was very rude towards me and did not even afford me basic time to voice out my concerns, I'm utterly disappointed with UFO and i want to categorically state that i don't want a factory fault couch which has been fixed back to my house, i have been without a couch for the past two weeks and they don't even care to give me a turnaround time or when i must expect to get back my couch, i am the one who must always call to check on them... was even contemplating to involve Ex-Repo cause in frustrated, dejected and confused in all in one..yhooo
