Items bought not delivered. It's over a month now. Caiphus (Manager) makes up different stories everytime i call

I purchased 2 x side tables at Royal Palace beginning of July. Payment was made on the 5th of July. Since then I have been following with them on the delivery and a Mr Caiphus who kept on promising that it scheduled for delivery and I should expect it the following day. It's been over a month now and he is not talking to me and avoiding my calls. I personally wanted to speak to the owner but i was told that they don't have contact details for him/her. The sales lady who tried to assist me via whatsapp has also been made to believe that the items are ready for delivery but nothing happens. I am disgusted by this kind of service
