Not a happy MTN customer

I Upgraded online 16 Aug still waiting for my device I have phoned in 3 times already the last time I was told that with my selection Honor 200 there shouldn't be a problem but it could be that the colour I chose was not available now my question is why does no one contact you???? When I upgraded the contract would have come with airpods and a R500 Pick n Pay voucher I guess now I will only get the airpods. Supposedly someone is going to phone me to change my colour so I could maybe get the phone this time. And wanting to cancel the contract and actually go do it in store I was told it will reflect badly on my name and I might struggle to get another contract why should that now be my problem MTN should take that upon themselves.
