Appalling service

I bought dining chairs and tables at Coricraft Rustenburg end of January, the sales lady said they will arrive end of Feb, come end of Feb, we drive to the store to find out where our delivery is, the sales lady just says "Oh, i thoght i told you guys that they will only be delivered end of March" I was so shocked that why are we only hearing this now? On the very same day we decided to buy a couch, the sales lady said she will combine the delivery of the couch with the dining set. She said that she will do a part delivery at no cost should the one of the items be ready before the other. Its now end on March, as usual we never hear from her with any updates, we send her an email to follow up on our order, guess what, now the dining chairs she got no clue where they are as she's saying they are not shipped yet and they will only be here end of April, and now everything will be delivered all at once if i want part delivery I have to pay for it. She initially misrepresented and said the dining set will be here end of Feb, had i known they would take this long i would have sticked to other chairs that were available at their earliest convinience. Worst part is that I have to follow her around with updates regarding my order. no level of proactivity from her side esp with all this delays, Coricraft is this a way of treating your customers that pay with their hard earned cash???
