Store moved without notice with item paid for

I'm furious at the way Verimark (East Rand Mall) and Head office had handled this matter in general. On the 30th of August my mom made a lay-bye of the Genesis Mega Steam Iron, we informed the sales guy (41313: as per slip) that we would come back on the 01st Oct to pay off the balance of R499. To my surprise when I got to the mall I found that the shop was not there instead where the shop used to be was just a vacant space with no information on where they have moved to. I used the Mall's Electronic Store Directory to try send find the store but the info was still referring to the old space. I tried calling the number listed but it only rang without being answered. I then searched for three Head Office number using my phone and called them. I was transferred to the Area Manager who said his name is Vincent. On explaining my complaint, he had the audacity of telling me that he wad at the store on Saturday and his staff had called all customers which was a blatant lie. When I confronted him about his staff not doing their due diligence because I would not have wasted a trip driving there he had the nerve to tell me how much he's trying to help me. His definition of "helping" me was referring me to the K90 store to get the iron. Before I could drive there I decided to find the numbers to that store myself and find oft if they actually gave this item and Florence who was very friendly and helpful in searching for my mother's details and confirming that she can see her on the system also confirmed that that iron was not available in their store. 04/10/2019. I decided to call Vincent again at head office and he distinctively remembered me. Only this time he actually did what he should have done to begin work which was checking which store has the merchandise. He said he'll call me back and 6 mins later he called to say that the Cresta store has the iron and he wanted to know if I can drive to Cresta or they should transfer it to K90. I advised him to transfer to K90 Centre branch. He said the other store will get it by Wednesday so once it arrives, the store will inform him and he will then call me to let me know that I can go fetch it. He had asked if I can wait until Wednesday and I said yes because I've already waited this long, but as its end of the day today 09/10/2019 at 17:38, I have not been updated not given any follow up regarding this issue. I am appalled by the service I received from Verimark in all its entirety.
