Not acceptable...

I did an online purchase for the Galaxy S23 Ultra, I specifically did this for my sons Birthday and before end May 2023 to qualify for the Galaxy buds 2 Pro which you get when purchasing the mobile phone 1 April - 31 May 2023. I initially wanted a green phone then called them a second time to change the colour to black. After waiting what seemed like forever for the phone to be delivered. I receive the green phone, this morning I call to ask if they can check why I received the green phone, when I called and specially asked to change to BLACK phone, this change was not made, I asked if I could do the exchange at a store instead of waiting that long period again, I was told no, I explain that I am now missing out on the Galaxy buds, the consultant could not help me in any way, besides asking me all the time should they ask courier to collect the phone. How is this helping me in anyway to get the mobile phone from Cell C, choosing them as my service provider, am I now going to miss out on the Galaxy buds because of a default on their side. This is unacceptable. I asked to speak to a team leader, who was not available, they asked my number which they already have as I am a customer who has other contracts with them as well. I would like to get the Galaxy buds that was the reason I took out this contract to gain the buds as well for my sons birthday. Lets hope this can turn into a positive outcome, where are the days you get great service...
