I need your help with what to do going forward. Thanks

Good day sir, I am nico chetty.. I have purchased a tablet onlie from PC LINKS COMPUTERS, with the knowledge that I have after reading they ad and purchase of the item that said they were having a sale on a Samsung tablet for R1350 and with the shipping cost it all came to R1700,and it would of got to me in the next 15 to 20 working days, failing to meet the requirements of what was told I have waited over a month and had still not received my item yet, so I emailed the seller and asked what's going on with my order and they rep**** saying that they were experiencing some issues with the shipment and they were trying they best to help get it out,so another full month went and when I asked how long more for my tablet to arrive they then tell me that I am not expecting a tablet but its a tablet cover, and when I made the purchase and eft the money they had said that my order for the tablet was successful, but they have mislead they customers and they wrongful information about the items that are being sold on the site, I also have being trying to call them but every time they phone goes straight to voice mail, and I also have the emails that I have from them since I placed my order.
