2nd hand dealers

I have bought a 2nd hand lounge suite from them for 3995.00.i have paid a deposit off R 500.00 on layby over 3 months period. This took place in the begging off Oktober 2020. My wife was phoned today and informed by the owners wife Letitia that she has sold it and that we can come and fetch our dep. This is by no means exceptable.
