Goods ordered but still waiting for some stuff

On 14 April 2020 I ordered 2 blank pistols with some rounds. I did a immediate payment of R5018. I followed up numerous times with all excuses from them. Then end of April I received my 2 pistols. No ammo yet. I followed up again. On 07 May 2020 I received some of my rounds. Still outstanding was my 30 pepper rounds worth R450. Kept following up. Today is 04 July 2020 and still nou rounds. Just empty promises.
