I want my sister's money back or delivery to be done at the address that was planned when laybye done.

My sister went into store to lay buy a cupboard this was in 2020 at protea glen branch. As we have a pandemic she had to rush home as a result of am emergency. Went in today as due date is close, was helped by a lady called Thandeka very rude Isy say as we asked to pay and was refused as I am not the owner though explain ed that I have the ID and am not changing any details would like to pay it do the money does not get forfeited. Was told no not possible also asked as I am from home (Limpopo) and checked if this could be paid and did not find a branch at Malamulele I was told it's not their problem if not paid due process would follow. My question was then does this shop only look out in getting people to buy and if you are not able to finish no alternative is done or referral as they just want to keep money for their sales representative. What kind of a business is this branch at protea green where there is no customer service at all.
