MTN TERRIBLE CUSTOMER SERVICE

I have had it with MTN now!! I phoned the upgrades department on the 10th of November to upgrade to a Samsung galaxy A32 5g. My parents and I did this on the same day. My parents both got their phones on the next day. I was told that I would have to wait 2 to 3 weeks. I phoned them on the 29th of November to find out what the hold up was as I felt that it was taking too long. They then told me that the phone was out of stock and they are unsure when it would be available again. I was then advised to maybe choose another device. I asked if I could hear my options for other devices and the reply was that I can't do so without the original consultant that did the upgrade signing it off. The lady then said that she would ask that guy to phone me and told me it would be within the next 30min. I waited and waited and no one phoned. I then phoned again the next day just to have the same story told to me again. So they emailed him and they can't do anything. I am really upset as this is the second time I've had problems with MTN 😡The first time was with the launching of the Galaxy S9 where I was promised a smart watch and then also told that it will be available for pickup soon... When I phoned to enquire about it, I was told that I am one of many customers who had been promised the same thing and it never happened. I feel like I should rather just leave MTN as they make empty promises and don't deliver what they offer. I phoned the customer service number ***) this morning but I have not had any answer and the line is just silent as soon as I'm told that the next available consultant will assist me. I am fed up with waiting for MTN to provide me with the service I pay for 🙄
