Upgrade of contract

I was contacted by a call centre outsourced by mtn to do early upgrades. After 3 attempts i was convinced to upgrade by an agent called Ryan. My contract was upgraded for another 2 yrs. Promised i would get the new samsung galaxy in 48 hrs. That was at the beggining of SEptember. We now at the end of september, all i received was an emailed copy of contract and called mtn to find out if my contract has been upgraded. Everything done however no receipt of the new samsumg galaxy. Phone mtn only to be told i need to contact this call centre called summer fun to try and locate the phone. Which i do call a cape town number and informed that they can give me the tracking no and i need to check with the courier. Absolute pathetic service. I am at my wits end. You cannot get a hold of somebody senior to deal with the query. Suddenly as a client i need to deal with 2 call centres. .where is MTN???? Help!!! ********** 906
