MTN Upgrading troubles

I would like to once again complain about the level of service received by MTN. It is time to upgrade my contract once again, the contract is in my husband's name and we went to the MTN shop in Secunda. As per the usual standard, they don't have stock of the phone I want to upgrade to. They did however order the phone for me, which is a promotional offer by MTN. The Samsung S21 Ultra along with the Samsung watch 3 41mm. This was last week Wednesday, the 31st of June 2021. They would call as soon as the phone arrived. Friday 02 July 2021, I was in town and thought I would just pop into the shop to find out, maybe they received stock and were a bit busy to call. The phone did arrive but apparently, they didn't receive the correct watch to go with it (They received the 45mm watch). So I tell them to just continue with the upgrade and give me that watch instead as that is also on promotion with the phone. The lady continues but then tells us that there is R2700.00 outstanding on my old device and that I would need to pay that over the next 3 months as well plus my new device and contract, as I am doing an early upgrade which I was under the impression is still possible as we have been doing it like that for years. Non the less, I tell them to cancel it. Since for the past two upgrades, I have been struggling with the MTN Secunda shop and have been doing my upgrades online in the hopes that it would be better and I could receive better service. So Friday, 02 July 2021, I phone in to the online upgrades, the lady that assisted me was extremely nice and proceeded with the upgrade. She tells me that there is the R2700.00 outstanding still on my old device, but I would be paying for the old device still until October and then only start paying for the new device, which was great and I agreed, I also upgraded the data line as well. She told me that they will do a credit check on my husband and that we will be kept up to date with how all of this went. Obviously, over the weekend I understood that there would be no feedback, but on Saturday I got a message that the credit check was approved and the upgrade can continue (Colour me impressed). Monday 05 July 2021, I received an SMS with the ref: *** that my order has been submitted, which I assumed would be the phone and watch being sent. Also on Monday 05 July 2021, the pro-rata data for the data contract was loaded as well as the promotional data. To my dismay, nothing was loaded onto my phone. So today, 06 July 2021, I ask my husband to phone MTN and find out what is going on and whether the device has been sent yet, to which they tell him that the order for the phone and watch was never submitted and thus, it hasn't been sent. So thank you MTN, for once AGAIN disappointing me with your services, after being with you for how many years. Again it just goes to show that you as well as your employees, have NO regard for your customers and as long as we pay our monthly bill on time, otherwise the lines get cut, you don't care whether your customers are happy or not.
