MTN making their fault my problem

I have been trying to upgrade my phone for almost three weeks to a phone (Huawei P20 lite, breathing Crystal and a Huawei Fit Bt(as advertised in November catalog pg 34) in a pink color watch).

I have been to stores in Hartbeestpoort, Potchefstroom, Rustenburg and Pretoria. I have phoned multiple stores and no one could help me.

After phoning MTN direct, multiple times, because they might get the stock I wanted. Which I was willing to order and wait for but I cannot buy something that you advertised. Finally I could get the color that I wanted in the phone, so I compromised on the watch color.

Then they phoned me on a wrong number and I had to call to justify it. That's OK.

When I orderd the upgrade over the phone, I specified that I wanted the Huawei Watch Fit BT as in pg 34 on your November Catalog. Please listen to the phone call: Reference number ***. Which I was accused of today that It was my fault because on the mtn system it only says Huawei Watch Fit. And so they brought me a Huawei watch Gt2e - Not okay if you advertised it wrong and make it my fault.

Now I have phone over 5 times and spoke to multiple people including supervisor and not one manager is available to speak, as no one could solve my problem.

I want to exchange my Gt2e watch for a Fit BT. The problem comes in with returning my whole package including the phone I have been searching for 3 WEEKS. WITHOUT the promise that I could get a phone in the same color. So most likely I am going to end up with a phone and watch in the wrong colors. I need to speak with someone who can authorize it so that I can keep my phone, take my watch to any mtn store and just send me the correct watch and adjust my contract to the correct monthly billing.

Please help me
