25-year loyalty violated

I’ve been a loyal and happy Vodacom customer for the past 25 years and I have never been disappointed about their customer service – UNTIL NOW. When I upgraded my contract to a Samsung A34 in November 2023, Vodacom promised me that I would get a Samsung Galaxy watch with that package. I remember I asked the sales agent, Preston, a lot of questions and I even asked him to give me a day to make my decision and call me the next day because I’m a very budget conscious buyer, and I still have notes I made when he said the deal would be R299 without the watch and R378 with the watch. He indicated however that the watch was out of stock and the cellphone would be delivered first and then the watch would follow later once it was in stock. I took the deal with the watch and received the phone in the first week of December. By the first week of January, I still had not received the watch. I started following up with them and was shifted from 1 person to another and was told my case would be escalated but it wasn’t. Eventually they blocked the numbers I was calling from because they said I was a frequent caller, hahahahaha. To get assistance, they gave me a number I would be charged R2-a-minute on and I‘d be made to hold up to upwards of 18 minutes. The person who assisted me on the 29th Jan, Ondela, is the only one who escalated properly and even called back to give me the ref number 197215 and said the relevant department would call me back with feedback. However, afterwards, no one called to give me feedback. I had to start afresh again and make follow-up. They indicated that the watch was not part of the invoice and so I asked them for the recordings because the discussion with their sales person influenced my decision to take the deal and the invoice is for the same amount as the Watch Deal as sold to me. They disappeared for weeks, and I had to keep calling them for feedback but they’d indicate they are still investigating. Eventually they said the recordings said the watch was for a 3year deal and I had told the agent that I want a 2year deal. I told them that the agent did not say the watch falls away with my request and I asked them to share the recordings with me so that I can hear him say that if I missed that part and accept that my error if there is. I am still waiting and each day that passes I feel like an idiot ****med by my own loyalty to Vodacom. I started enquiring on this case about 8 weeks ago but still no solution.
