Protea Brick & Timber Hardware Unclaimed

I have bought material at Jock's Hardware cc trading as Protea Brick & Timber in Protea South in Soweto, delivery note 035656. I was so suprised to find that the store has been liquidated without anybody mentioning anything to their clients. I was there two weeks before I knew it was liquidated and nobody ever mentioned this to me. I am now sitting not knowing if I will ever receive my river sand that I had bought and paid for. This is very upsetting , how could you close a shop without notifying your clients. When I rang their numbers the number doesn't go through. It is very discusting and disturbing.
