Bad Customer Service

I went at V&A Waterfront store on the 01 January 2025. On the brochure there a Samsung TV deal that I got interested on and I added it on my contract. Got the voucher came home,I registered the voucher it didn't work,on the 2nd I went back to the store they tried it and it gave the consultat some tough time but he eventually did it successfully. I have been waiting for the TV from that day till now. I called the store today,unfortunately the was no solution to my issue, except being given a number to call wich I had to hold and listen to the boring song on its IVR for more than 20 minutes without any response. Mind you the number is a shared call number,so I literally wasted my airtime on top of the petrol I wasted for going back to the store to activate the voucher.
