Poor Service at Decofurn Factory shop in Somerset Mall

On Sunday the 17th February 2019 I bought a tv stand at Decofurn Factory shop in Somerset Mall. I approached a sales lady and ask to check if it's available and they checked on their system it yes there is some available. Sales lady Ayanda took my details and load them on their system and then she asked me to make a payment to their Cashier. I've done that and I was directed to go to the back or workshop whatever they call it to collect my stuff. I've waited more than 10 minutes no one says anything. Ayanda also came to the back with an invoice for another customer and I asked what about me. Ayanda and other 2 African guys were arguing and swearing at each other. My cousin told them its rude what they are doing in front of customers and they only tell me that the stand is out of stock and I must go back to the cashier for a refund no apology nothing. I went back to the cashier but I decided to ask for a manager. While I was busy with the manager by the name Craig the cleaner was busy asking me some stupid question but I told her to wait I'm busy with her manager now so she must leave me alone. Craig went to the back and came with same answer nothing at the store room. He made a copy of my invoice and told me that it would be delivered on Monday or Tuesday the latest I must write my home address and contact number.I've done that but nothing happened till Tuesday afternoon. I called then the lady told me Craig is off but she will check and call me back. She didn't call me until I called them and Ayanda answered the call and promised that Wednesday I'll get my stand. Wednesday morning Ayanda told me the driver will call me when he is on the way. I waited the whole day and I called them to check it was a long story but promised that I'll get my stand same day. The driver call me advice he is on the way to me and I waited more than an hour and I called him back to find that he doesn't have my goods he made a mistake. I asked him to call the store because I need my delivery today and he promised to call the store. I called Ayanda and asked actually what's the problem and she must check and call me back but she never call me. I really hate their customer service its very very bad. The reason why I write this complaint I'm ****ed of with the service I got at Decofurn. They need to do something about this *********** service. I hate their customer service its pathetic.
