CLOSE DOWN OK FURNITURE

So for a couple of years now I have been buying cash furniture at OK Furniture Da****rt Bougainville shopping centre. my first tick of came last year I spend nearly R 50 000 in cash for new furniture one item to be a new TV. The furniture where delivered. The TV stayed in the box until I could find an installer to put it up against the wall. When the installer came and we opened the box the TV had a huge crack in the corner. The store did not want to exchange the TV so i was stuck with a broken TV. This year I saw a chest freezer I decided to put a lay buy deposit on it till i came back with the full amount. During the course of last week I found a cheaper one somewhere else and bought it cash since OK didn't give me a contract on the purchase on a receipt on the payment I had made I was reluctant that the same thing is going to happen as with the TV. So yesterday I went in to cancel this layby first everybody is lazing around on the chairs no help finally the cashier Gertrude lifts her head and look at me as I where disturbing her sleep. I smiled said good morning showed her my receipt explained to her I want to cancel my layby. Gertrude ask for my contract I said the day I came in to pay the deposit the sales clerk said that there is no paper and she will print the contract on the day I pay my final instalment, the she told me she cannot cancel the deal because she doesn't have R 150 to return to me, then the apparently manger JOSEPH stepped in and said she doesn't have to give me back anything as they don't keep cash on the premises. I just wonder what do you do if a client comes to pay for goods and should get change. Suddenly they spoke in a different language and decided that they are not going to assist me. THIS IS BS I GOT STUCK WITH A BROKEN TV I DIDNT GET A COPY OF A CONTRACT OF A CHEST FREEZER I LAYBY AND NOW I CANT GET MY R 150 BACK BS BS BS!!!!
