Poor Customer Service

I'm very disappointed with service rendered by House & Home. I have a layby with them which I done online for a PS5 Digital for R9499. The layby final date was today. I went in store the House & Home at Carnival Mall to make my payment and get my son's PS5. I got there they couldn't pick up my reference number and the R100 deposit payment that I've done to House & Home online. So I provided the lay with the e-mail and reference that I've received from House & Home online. The lady contacted the Head Office for assistance. She was advised they'll call her back since they've realized that the fault is on they side. I decided to go run errands while wait for them to call back. I received a massage from them advising that I'll have to pay R4700 this month and the another R4700 next month for the Ps5. So I didn't mind the massage because I new I was going to pay the full R9400 balance cash today as it was it's last day before the layby expires. I came back and the lady advised the Head Office is busy trying to locate the funds to the correct deal. That also left me puzzled that how did we get there because I thought a big company like House & Home priorities their customers. I then advised the lady that I had to go pick up my son from school so I'll have to come back at 3pm. I came back and the store manger advised that the funds are not yet located to my layby and the Ps5 Digital is out of stock. Namibia is the only place that has stock and they won't be able to get the PS5 digital from there as it is very far. So I'll have to top up with R2500 to get the new PS5 Digital Slim that is worth R12000. I find it so unfair and unprofessional that I had to wait close to 45 minutes and I had to drive back to be told that the item is out of stock and nothing can be done. Can House & Home please do right by me.
