Non accountability of my purchased items

Around 2014 , I purchased the following items at Game store Mafikeng, Russell Hobbs digital stove ,dishwasher & the fridge cash .All those items were on sale.During that period I was busy with construction in my house & I informed the store to keep those appliances for me to be collected later & I was guaranteed that it's not a problem. Later when I approached the store to enquire I was never given a clear answer. I have been taken from pillar to post even though I had produced proof of purchase , the store correspondent that I was introduced to solve my problem even left the store without telling me about the whereabouts of my purchased items.To date there no answer, I was even advised by the new store manager to write an affidavit for an intervention of the store legal department. I did comply to that effect , I am sitting here with documents that proves that the purchase was made but with no items.
