pathetic service from LEWIS AGAIN

Completely pathetic service AGAIN, (6months later). My wife goes to Lewis in Vryburg to get a Sinoteq 50`inch, (58inch) for R9999,99 and also a stand, no problems only that she sat their almost the whole day on friday, then also paid for a delivery fee of R700.00 and when come on saturday to find out a time for the delivery, she waits again on saturday morning to be told an hour later they cant deliver cos the car has a flat tyre and the other driver went out of town. OK no problem, i call them to confirm another date and they said sunday morning the 1st of December 2024, no stress but they giving us the display units from the floor, i told them how is it for a customer to pay the same price of a brand new unit for a second hand unit why cant they give us the units still sealed in a box as i am entitled to it if i am paying, The store manager goes on to call me back later on to explain that they dont have that t.v in stock and its discontinued but they will check with another store for the same unit, come back sunday they call to tell my wife she must come to the store and cancel her application and do it online. i call customer care yesterday to log a complaint ref 900878 and just get a call now stating the same things the store told us and nobody giving us a solution to resolve, just that my wife must cancel and redo the application to take a bigger t.v out, Now the problem i have is that nobody wants to accept ownership that they did a contract knowing they didnt have the stock or they didnt check first and just tried to get rid of display units, i wont accept this treatment and we need this resolved 6 months ago we got a fridge from lewis in middelburg and they did the same thing, giving my wife a display unit that was full of mould inside we ended up getting a unit that was more expensive for the same value, and now a different store is doing the same thing to us again. i feel like taking those photos and all of my evidance and discussing it with my lawers at this moment because this is disrespect and complete disregard for customer care
