Waiting for delivery from House & Home Centurion

I purchased 2 bed and base on 28th November 2025(Black Friday) sale at House & Home Centurion. The sales person that helped me with the sale is Michael Bonoko. After several phone calls regarding the delivery of the purchased items, I eventually went to the store on Monday 8th of December 2025 and Michael told again that they order 1000 of the Lunar Neria 152cm p/top base set and they are still waiting for stock. After deliberating the way forward it was agreed that the one base set (Edblo) which was available ,will be delivered and only when the second base set is delivered I will pay for the delivery charges. This base set was delivered the same afternoon but they requested that I pay for the delivery charge and the outstanding delivery will be no charge. I requested that in writing. Their latest catalogue dated from 8 to 26 December 2025 has the very same Lunar base set advertised. I contacted the salesman and he tells me that only 15 of them has been released and he cannot tell me when I will receive my base set. I contacted their customer care line ***) on 12th of December 2025 at 12:04 and was given the option of leaving a message, which I did. I contacted them again at 16:12 and waited on the line for 10minutes and I eventually left a message again, and I am still waiting for them to contact me.
