Not able to upgrade Horrible service

I entered a store 11:30 on Wednesday the 30th of May to upgrade my already available contract. First issue - appeared there was a ***** attempt , got a letter of identity validation Second issue , now my contract is under a business, which it was but this would be my second upgrade after I took over the contract to me personally, now they can't do the upgrade and needs to escalate Then it is a different issue which the store assistant is not able to tell me exactly what it is? I sat in the store till 17:00 as I live 40km out of town on a farm and wasted a good 5 hours of my life. It is now Friday and the assistant who is trying to help me said that the problem is not with me , as they don't need any outstanding documents, but it is a problem at MTN. How is something that has nothing to do with me my problem and why must I endure this absolute horrible service. All I want is my upgrade nothing less nothing more. Why do I as the customer need to be subjected to this inconvenience and time wasting excersise. If my issue is not sorted I am canceling my contract tommorow to move to a different service.
