Homechoice not deliving all the combos i bought

My name is Praylord Mnisi On the 30 may 2020 I went to Nelspruit Homechoice to buy four Mink Blankets combos cash, they told me that their out of stock and they will come and deliver from my work place. On the 9th of June they came and deliver three combos instead of four, i told the guy who came to deliver that one combo is missing the guy told me that he was only given three combos i must call homechoice of which i did immediately the lady who answered my call was very rude she told me they know that they send three combos and the other one its on the way. on the 22nd of june i call them to check how far is my parcel, they say to their system I've received all the combos. The problem that i have now i bought it for many people and now they want their blankets. Thanks
