CNA Jaguar E Never received last 3 parts as promised

Good morning, We have been buying the Jaguar car parts from part 1 - part 97. This cost us approximately R15000. I was promised by the store that they would locate me the last 3 parts: 98,99 and 100. However, they closed down and now I don't know where to find someone who can assist me. It seems that the whole of CNA just disappeared. For months on end, I went to the store and I was just told that they are still waiting for the parts. I do not believe that it is just okay as a loyal customer who always supported the store and has built a rare collectible car, to now sit with it almost done and not having to finish it. Spent all that money and now nothing that I can do? Very poor service and communication.
