10/10 for pathetic service

I went to the store in Krugersdorp on 4/3/2019 to purchase a couch. I was assisted by a sales person that advised me that they don't have stock and have to order it. I enquired how long it will take and was advised that it will only to take a day for the order and should be there by 6/3/2019. I also enquired about the warranty and was advised 3 years on the material should anything happen to it I will be fully covered. On the 7th I called to the sales person only to be told that they haven't received stock as yet but will follow up and come back to me. Surprise surprise the sales person didn't bother to call me back. I called the store on the 8th again only to be told that the warehouse now has a stock take and he is unable to confirm when the couch will be delivered to the store. I then spoke to the manager for the store who also couldn't do much as it's Friday afternoon and due to the stock take nothing can be done but he will arrange for Monday for the couch to be delivered. Got a call from the manager on 11/3 and only to be told that I'm still not getting the couch today. I can honestly say that this is by far the worst customer experience I've ever received. The more shocking news that I only received from the manager on 11/3 is that the couch only has a warranty of 1 year and not 3 years on the material confirmed by 2 sales persons of the store. The sales personnel are seriously misleading customers. When I questioned the manager about this all I was told sorry and that he will address it. What would have happened to my claim if I went back in 2 years time? Clearly, absolutely nothing!! This whole experience left a very bitter taste in my mouth.
