Overpromise to under deliver! False advertising

So on the 1st of March I paid for couches which I was told were out of stock but that if I pay on the day couches will be ordered, i got an invoice on the same day noting that my couches will be received in 3 -4 weeks, so I was expecting the couches by end of March tops. Fast forward to today I am still being given the run around. In the fourth week of making my purchase I followed up with the consultant who was helping me with the sale, and they kept taking me to pillar to post. One consultant even told me they would give me my refund, imagine after making me wait for an entire month, is that how you treat your customers. Everyday since then I keep getting told that the couches will be delivered in the next week, its one postponement after another. The customer service is straight out bad, very poor communication. I have to chase them everyday, unless I say something no one says anything. Do not over promise only to under deliver, if you know that your supplier is having shortage of material, you should be honest with your customers and not be quick to want to take money only to make customers have to fight with you. Honestly its ridiculous. You dont have this velvet grey new york couch in stork, dont advertise it. You are misleading customers and it is not okay
