BAD SERVICE

I have the worst kind of service from MTN these past 2 weeks. Upgrading is an issue because you are being transferred from pillar to post eventually when one gets some sort of agent. " its my system not working with an attitude of not being helpful. I have spoken to probably 7 people , who all have different versions of the information I require. All I need is a contract phone and the benefits to be transferred to my prepaid sim card. This should be a seamless process but WOW it has been a nightmare. I was told to go to the store only for me to be told that there's a phone already ordered!! WHY?? because I had cancelled that request. I need someone to call me with a solution because I am losing time and business trying to sort this out
