worst service ever

I pay on average 650 per month for my contract. now I need to upgrade and I cant even get a contract of 549. or even 449. what now they are telling me I might need to downgrade. what *******. on top of that, if I downgrade I will have to pay a fee, are you people mental. I can afford 650 so I can obviously afford 549 especially 449. then I try and call 8 times to get data loaded and the line drops after me waiting for 12 minutes. I call mtn direct to see the status of my upgrade and i still did not get feedback from the supervisor that should sign it off. I get through to this idiot at 9:47 and 9:50 he doesnt help. the first time he drops the call in my face. 2nd time he passes me to the person that was dealing with my application. I didnt ask him that. all I asked was which deal do you have on other phones. I was still talking and I started hearing hold music. if I dont get my upgrade. im leaving mtn and I will be taking people I know with me.
