Bad service

Hi. I just must say since I was migrated to your new system. I have had nothing but issues, with no resolve. A week ago i wanted to load more airtime, was told my cant as I have been moved to the system. Then last friday wanted to upgrade one of my contracts that when checked last month and with the call centre was told I can on the 20th feb. When I got there, the store told me I can only upgrade in march as I'm on the new system or I can pay a early upgrade fee ofR657. Then today on my other contract wanted to load data. Was told cant cause on new system. I was moved on first of feb. And up till today you at mtn do not come back to me or can help. To say that I am ****** upset it putting it lightly. I have been told someone will call me tomorrow. I said if not recieved a call by 9am, I am at 10am going vodacom. So let's see how this neywork can brighten my day......
