Upgrade

I went to the mtn at rivonia village in December to do an upgrade on my moms phone a Samsung A53. My moms phone was due for an upgrade by that time and had been paid off where as my phone S23 ultra was not even close to an upgrade yet. My mom had chosen an upgrade package online that she wanted it was a phone and watch combo. Because my mom lives is kempton and I in sandton I had to do the upgrade without her and wanted to surprise her. I then went in store and showed the lady what I wanted which was the A55 with a samsung watch 6. She then got the phone in stock for me and continued to say that the watch had been discontinued and id have to buy it at samsung if I wanted ( this was a complete lie as another person at another branch had stock of the watch and said it was only OUT OF STOCK).After hearing this I obviously believed her and ended up just taking the phone (this was before I asked at another branch).After taking the phone I wrapped it and kept it for 3 days then gave the phone to my mom as a surprise. But to my surprise when my mom tried to use the phone it had a payjoy block on it which was not supposed to be there as she said everything is fine. Then my debit order went off and to my surprise they tried to debit R25000. So I went in to MTN at rivonia on the 6th of jan after trying to sort out the pay joy block at game and mtn mall of africa (where I found out that not only do they have a watch but the phone they gave me might have been used which was the cause for the payjoy block)which was a nightmare. Upon going back to the Rivonia branch to try and sort things out they tell me that NO she upgraded my number and not the number I gave which was my moms phone number NOT MINE ,therefor I was debited for an early upgrade. I have been consistently going back for 3 weeks now and head office has not done a SINGLE thing yet when they had looked on my profile on friday they had said that nothing has been done and that we are waiting from someone at head office to communicate with me via email ( I HAVE NOT RECEIVED EVEN 1 EMAIL TILL TODAY).All because one person at the rivonia branch did not feel like doing her job. PLEASE GET THIS FIXED
