2 days trying to activate a sim card

My contract was upgraded through mtn corporate and I received the new phone on Tuesday 13 October 2015. The phone came with a new micro sim which needs to be activated. The number provided by mtn to activate the sim card is ***. i have been trying since then to activate the sim card and have been unsuccesful Upon every attempt its the same error message - \your request cannot be processed due to a network issue"<br> I then called the call center 808 and was told they could not assist and i need to call the corporate division on ***. i have been calling the this number and have been on hold for the past 35 minutes. this level of customer service is ridiculous. i have a good mind to cancel the upgrade and move to a service provider who shows a little more interest in their customers. it is appalling that only days before the mtn ceo made headlines\""we will become a more caring organization\"".... yea right...."""
