Vodacom have now messed up my upgrade 3 times in a row! What a mess! Highly ***********!

I was contacted by Vodacom to upgrade my number which contract ended. I was called and offered a 10-inch tablet on 07/10/2024 and was delivered an 8-inch tablet. I called to complain advising that I was not sent what I agreed to in the upgrade call. They asked me to book a cancellation and return it. A week later they called again to re-process the order. This time the upgrade consultant advised I would get a Samsung A9 10-inch tablet. I received a Samsung A9 8.7-inch tablet instead. They asked me to book a cancellation and return it. A month later on 11/12/2024 Vodacom called me again and offered a Samsung S9 10-inch tablet which I chose the colour blue. They just delivered a colour grey tablet when I asked them 5 times on the call to please ensure the tablet delivered is blue which they said they will ensure. Now the third time Vodacom has messed up! Complete blatant incompetence and an absolute mess! Useless and not capable at all! I have had enough, and I am finished with Vodacom!
